Remove QUERY_STRING from URL only for /index.php - apache

I would like to remove the query string from the URL using mod_rewrite (.htaccess), but only for /index.php (and not /).
For example, http://www.example.org/index.php?foo=bar should redirect to http://www.example.org/index.php, but http://www.example.org/?foo=bar should be left alone.
This is my current sutup:
RewriteCond %{QUERY_STRING} !=""
RewriteCond %{REQUEST_URI} ^/index\.php
RewriteRule ^(.*)$ /$1? [R=301,L]
It works, but not with the limitation I want (i.e. it still removes the query string even when index.php is not in the URL. I think this may have to do with REQUEST_URI realising that / is being internally redirected to /index.php, but I can't be sure.
As a side question, I would have a lot easier time working this stuff out if I could work out what value was being used REQUEST_URI, is there an easy way to log this somewhere?

You can add this lines to your httpd.conf to see what's going on
RewriteLog /path/to/log
RewriteLogLevel 5

.htaccess RewriteRule from long url to show short url

Im trying to rewrite url from long to short but cant wrap my head around this.
My survey rewrite works wonderfully but after completing my survet php redirects to www.example.com/survey_thank_you.php?survey_id=1
but I would like to show url like www.example.com/thank_you
Im not even sure if this is possible.
Im new with .htaccess and i have tried almost everthing
.htaccess
Options +FollowSymLinks
Options -MultiViews
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule ^survey_thank_you.php?survey_name=([0-9a-zA-Z]+)/?$ Thank_you [L,NC,QSA]
RewriteRule ^([0-9a-zA-Z]+)/?$ survey_form.php?survey_name=$1 [L,NC,QSA] #works like charm.
Any help or directions will be highly appreciated.
Solution:
Options +FollowSymLinks
Options -MultiViews
RewriteEngine on
RewriteCond %{ENV:REDIRECT_STATUS} ^$
RewriteCond %{QUERY_STRING} ^survey_id=([0-9a-zA-Z]+)/?$
RewriteRule ^survey_thank_you\.php$ /%1/thank_you [R,L,QSD]
RewriteRule ^([0-9a-zA-Z]+)/thank_you$ survey_thank_you.php?survey_id=$1 [L,NC,QSA]
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule ^([0-9a-zA-Z]+)/?$ survey_form.php?survey_name=$1 [L,NC,QSA]
but after completing my survet php redirects to www.example.com/survey_thank_you.php?survey_id=1
You need to "correct" the URL that PHP is redirecting you to after the survey. If the desired URL is /thank_you (or /Thank_you?) then PHP should be redirecting to that URL.
You then use mod_rewrite in .htaccess to internally rewrite /thank_you back into the URL that your application understands. ie. /survey_thank_you.php?survey_id=1. However, therein lies another problem, where does the 1 (survey_id) come from in the query string? Presumably you don't want to hardcode this? So this would need to passed in the requested URL. eg. /1/thank_you or perhaps /thank_you/1?
However, is this really necessary? The resulting "thank you" page is not a page that should be indexed or a page that is normally navigated to by the user, so implementing a user-friendly URL here doesn't seem to be a worthwhile exercise?
RewriteRule ^survey_thank_you.php?survey_name=([0-9a-zA-Z]+)/?$ Thank_you [L,NC,QSA]
RewriteRule ^([0-9a-zA-Z]+)/?$ survey_form.php?survey_name=$1 [L,NC,QSA] #works like charm.
You are using a survey_name URL parameter (referencing an alphanumeric value) in your directives, but a survey_id ("numeric"?) URL parameter in your earlier example? So, which is it? Or are these rules unrelated?
You state that the second rule "works like charm", but how? What URL are you requesting? That would seem to rewrite /Thank_you to survey_form.php?survey_name=Thank_you - but that does not look correct?
As mentioned in comments, the RewriteRule pattern matches against the URL-path only. To match against the query string you need an additional condition that matches against the QUERY_STRING server variable. This would also need to be an external 3xx redirect, not an internal rewrite (in order to change the URL that the user sees). Therein lies another problem... if you don't change the URL that your PHP script is redirecting to then users will experience two redirects after submitting the form.
You also need to be careful to avoid a redirect loop, since you are internally rewriting the request in the opposite direction. You need to prevent the redirect being triggered after the request is rewritten. ie. Only redirect direct requests from the user should be redirected.
So, to answer your specific question, it should be rewritten something like this instead:
RewriteCond %{ENV:REDIRECT_STATUS} ^$
RewriteCond %{QUERY_STRING} ^survey_name=[0-9a-zA-Z]+/?$
RewriteRule ^survey_thank_you\.php$ /Thank_you [QSD,R,L]
The check against the REDIRECT_STATUS environment variable ensures that only direct requests are processed, not internally rewritten requests by the later rewrite. REDIRECT_STATUS is empty on the initial request and set to the string 200 (as in 200 OK status) after the first successful rewrite.
The QSD flag (Apache 2.4) is necessary to discard the original query string from the redirect response.
So the above would redirect /survey_thank_you.php?survey_name=<something> to /Thank_you.
But this is losing the "survey_name" (or survey_id?), so should perhaps be more like the following, in order to preserve the "survey_name":
RewriteCond %{ENV:REDIRECT_STATUS} ^$
RewriteCond %{QUERY_STRING} ^survey_name=([0-9a-zA-Z]+)/?$
RewriteRule ^survey_thank_you\.php$ /%1/Thank_you [QSD,R,L]
Where %1 is a backreference to the value of the survey_name URL parameter captured in the preceding CondPattern.
However, you would then need to modify your rewrite that turns this back into an understandable URL.
(But you should probably not be doing this in the first place without first changing the actual URLs in the application.)

REQUEST_URI rewrite incl. query string

I have a WordPress plug-in and theme that are malforming a URL call to an external css file. I will fix that later, but until then, I need to do a redirect so the css is getting served correctly.
REQUEST_URI contains the full path, so why doesn't this work?
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_URI} ^/?wp-content/plugins/jetpack/css/%22https:/fonts.googleapis.com/css?family=Open+Sans%22$ [NC,OR]
RewriteCond %{REQUEST_URI} ^/?wp-content/plugins/jetpack/css/"https:/fonts.googleapis.com/css?family=Open+Sans"$
RewriteRule ^(.*)$ https://fonts.googleapis.com/css?family=Open+Sans [R,L]
</IfModule>
Note 1: I have tried several combinations of escaping characters in the RewriteCond. Nothing works.
Note 2: I am using flag [R,L] for testing, to prevent browser caching. Will change to [R=301,L] later.
Note 3: I have tested to verify that the problem is with the RewriteCond, not the RewriteRule.
UPDATE:
OK, so this was a bad question and a dumb mistake. Even though raw REQUEST_URI contains the query string, mod_rewrite specifically does not allow query string to be in REQUEST_URI for matching purposes. Hence, QUERY_STRING instead. I thought that it could be done either way.
I don't have a true query string in my REQUEST_URI -- I have the query string that is in a string that I wanted to match -- so that is why I didn't go to QUERY_STRING at the outset. But mod_rewrite still sees the ? as a typical query string start.
Sorry, guys. I can handle it like this until I fix the underlying problem in WordPress:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_URI} ^/?wp-content/plugins/jetpack/css/%22https:/fonts.googleapis.com/css(.*)$ [NC,OR]
RewriteCond %{REQUEST_URI} ^/?wp-content/plugins/jetpack/css/"https:/fonts.googleapis.com/css(.*)$
RewriteRule ^(.*)$ https://fonts.googleapis.com/css?family=Open+Sans [R,L]
</IfModule>
With WordPress, always remember to put your rewrites above the WordPress rewrites.

htaccess rewrite rule from folder to folder with querystring

I am looking to include a rewrite rule for the following but can't seem to get it to work. I don't want to pass any query string in but I need to add one to the rule.
I want this URL:
https://example.co.uk/vehicles/
to point to:
https://example.co.uk/search-results/?category=1
but keep the first URL in the address bar.
I need to pass in a variable called category with a value.
I tried the following but it didn't work for me:
rewriterule ^vehicles/$ search-results/?category=1 [NC, L]
Any help would be appreciated.
RewriteEngine On
RewriteRule .* ? [F,L]
RewriteRule ^(.*)$ https://example.co.uk/$1 [R,L]
RewriteRule ^ad/(.*/)?([0-9]+)$ view-ad/?ad=$2 [NC,L]
RewriteRule ^vehicles/$ search-results/?category=1 [NC,L]
I managed to solve it. It was due to an Ajax load on the page.
Glad you solved your initial query, however, the following two directives in your posted .htaccess file will break your site, so presumably, these have already been removed?
RewriteRule .* ? [F,L]
RewriteRule ^(.*)$ https://example.co.uk/$1 [R,L]
The first directive simply blocks all access to your site, returning a 403 Forbidden response. And the second directive will result in a redirect loop.
Now that it works is it possible to have another rewrite rule that does this https://example.co.uk/vehicles/?something=1 and rewrite to https://example.co.uk/vehicles/?category=1&appendsomething=1 but only display https://example.co.uk/vehicles/
I assume you mean https://example.co.uk/search-results/?category=1&something=1 (as opposed to /vehicles/) - where something=1 is appended on the end of the query string?
You wouldn't be able to make this "display as https://example.co.uk/vehicles/" - as this would conflict with your existing (working) directive.
However, you could potentially modify your existing directive to handle requests for /?something=1 and pass this through to the substitution. This would simply require the addition of the QSA flag (Query String Append). For example:
RewriteRule ^vehicles/$ search-results/?category=1 [QSA,NC,L]
The QSA flag results in the query string from the request being appended to the end of the query string specified in the RewriteRule substitution.
UPDATE: To redirect HTTP to HTTPS, you would need something like the following instead:
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://example.co.uk/$1 [R,L]
Note the preceding RewriteCond directive - this ensures that only HTTP requests are redirected, not everything (HTTP and HTTPS), so avoiding a redirect loop. Ultimately this should also be a 301 (permanent) redirect, so you should change R to R=301, but only when you are sure it's working OK.

removing directory in apache mod_rewrite

I have a PHP site which replaces an ASP site, so the path structure is different.
In the URLs, I need to match http://apache.site/Cartv3/Details.asp & redirect to another location. What is the correct syntax to match that URL fragment?
I've already tried
RewriteCond %{REQUEST_URI} CartV3/results1.asp?Category=60
RewriteRule ^(.*)$ home-study/A-Levels/1/page-1 [R=301,L]
and
RewriteRule ^CartV3/Details\.asp?ProductID=1004 home-study/A-Levels/1/page-1 [R=301,L]
You meed to read more about mod_rewrite. Remember RewriteRule doesn't match query string. You attempt needs to be rewritten as:
Options +FollowSymLinks -MultiViews
# Turn mod_rewrite on
RewriteEngine On
RewriteBase /
RewriteCond %{QUERY_STRING} ^Category=60$ [NC]
RewriteRule ^CartV3/results1\.asp$ /home-study/A-Levels/1/page-1? [R=302,L,NC]
Once you verify it is working fine, replace R=302 to R=301. Avoid using R=301 (Permanent Redirect) while testing your mod_rewrite rules.
PS: ? after page-1 is a special mod_rewrite syntax to strip original query string. If you want to keep original query string in rewritten URL then take out ? in the end.
The problem here is that you are trying to match the query string, which has to be done by a separate RewriteCond. If you want the match specifically "Category=60", then you can add it as a Condition:
RewriteCond %{QUERY_STRING} Category=60
RewriteCond %{REQUEST_URI} /CartV3/results1.asp
RewriteRule .* home-study/A-Levels/1/page-1?
This will match http://example.com/CartV3/results1.asp?Category=60 and redirect. The ? at the end of the rule stops "?Category=60" being to the resulting URI.
If you don't care about the value in the query string, then you can remove the first condition.

Apache mod_rewrite going berserk - redirecting where it shouldn't

I have a script that echoes a meta redirect to a page called account_management.php5, but for some reason it automatically redirects from there to index.php5. My .htaccess file handles a couple of redirects automatically, for example index.html|php5 to the domain root, and that's the only place I can see this problem originating, but I don't understand why. This is my .htaccess file:
RewriteEngine On
#remember to change this to aromaclear
RewriteCond %{HTTP_HOST} !^sinaesthesia\.co.uk$ [NC]
RewriteRule ^(.*)$ http://sinaesthesia.co.uk/$1 [R=301,L]
RewriteCond %{THE_REQUEST} ^GET\ .*/index\.(php5|html)\ HTTP
RewriteRule ^(.*)index\.(php5|html)$ /$1 [R=301,L]
#translate any .html ending into .php5
RewriteRule ^(.*)\.html$ /$1\.php5
#change / for ?
RewriteRule ^(.*)\.html/(.*)$ /$1\.html?$2
#strip .html from search res page
RewriteRule ^(.*)search/(.*)$ /$1search_results\.html/search=$2
#translate product details link from search res page
RewriteRule ^products/(.*)/(.*)/(.*)$ /product_details.php5?category=$1&title=$2&id=$3 [L]
#Translate products/psorisis/chamomile-skin-cream-P[x] to productview.php5?id=1
RewriteRule ^products/.*-P([0-9]+) /productview.php5?id=$1 [L]
Wrong:
RewriteRule ^(.*)\.html$ /$1\.php5
Right:
RewriteRule ^(.*)\.html$ /$1.php5
Righter:
RewriteRule ^(.*)\.html$ /$1.php5 [QSA]
This same mistake of escaping special chars in the second param of RewriteRule is happening in other rules too, I don't know if apache will handle it, but I know you don't need it because second param is not a regexp.
Never compare to %{THE_REQUEST}, thats a weird thing to do, you don't need that. Moreover, this condition is fine without it. Just put there:
RewriteRule ^(.*)index\.(php5|html)$ $1 [R=301,QSA,L]
Now look at it:
RewriteRule ^(.*)\.html/(.*)$ /$1.html?$2
First, you are still accepting that there are references to .html files, just after trying to translate all .html to .php5, there's something wrong here.
Moreover, you are defineing as QueryString something that was originally a file path, and are not even putting it in a key. It won't work, it need some more treatment.
#strip .html from search res page
RewriteRule ^(.*)search/(.*)$ /$1search_results.html/search=$2
Wasn't it supposed to strip the .html? Because it is actually putting a .html there. Maybe as it is not an [L] it get fixed in the next loop, but you could just get all fixed right here.
#translate product details link from search res page
RewriteRule ^products/(.*)/(.*)/(.*)$ /product_details.php5?category=$1&title=$2&id=$3 [L]
This one full of .* is potentially unstable, specially delimitating the end. You should do this:
RewriteRule ^products/([^/]*)/([^/]*)/([^/]*) /product_details.php5?category=$1&title=$2&id=$3 [L]
# or:
RewriteRule ^products/(.*?)/(.*?)/([^/]*) /product_details.php5?category=$1&title=$2&id=$3 [L]
The last one looks correct, except that you should strip the special character that may be faced as a range delimiter, the "-". I don't think it work after a *, but just to be sure and correct the syntax:
RewriteRule ^products/.*\-P([0-9]+) /productview.php5?id=$1 [L]
Add this just after RewriteEngine on
RewriteLogLevel 9
RewriteLog /tmp/rw.log
Then restart the webserver. It should help you debug the problem.
Edit: Sorry, I didn't notice the .htaccess above. This will only work from the main apache configuration file.
