I want to use htacess to redirect the following examples:
www.site.com/downloads/file1.txt
www.site.com/downloads/folder/file2.txt
to
www.site.com/download?file=file1.txt
www.site.com/download?file=folder/file2.txt
Ignore that there are slashes in the query string for the sake of the example.
You can use mod_rewrite for that.
RewriteEngine on
RewriteRule "^/downloads/(.+)" "/download?file=$1" [R=301,L]
Set the proper HTTP status code for the rewrite action (301 - permanent, 307 - temporary).
As I never used mod_rewrite in .htacces, you may need to try out some more combinations. Maybe the directory name needs to be removed from the regular expression, as it is already clear from the .htaccess context - the manual should help.
RewriteEngine on
RewriteRule ^/downloads/(.*) /download?file=$1 [R=301,L]
301 - Moved Permanently
The resource has permanently moved to a different URI.

RewriteEngine on
RewriteCond %{QUERY_STRING} (^|&)public_url=([^&]+)($|&)
RewriteRule ^process\.php$ /api/%2/? [L,R=301]
Where domain.tld/app/process.php?public_url=abcd1234 is the actual location of the script.
But I am trying to get .htaccess to make the URL like this: domain.tld/app/api/acbd1234.
Essentially hides the process.php script and the get query ?public_url.
However the script above is returning error 404 not found.
I think this is what you are actually looking for:
RewriteEngine on
RewriteCond %{QUERY_STRING} (?:^|&)public_url=([^&]+)(?:$|&)
RewriteRule ^/?app/process\.php$ /app/api/%1 [R=301,QSD]
RewriteRule ^/?app/api/([^/]+)/?$ /app/process.php?public_url=$1 [END]
If you receive an internal server error (http status 500) for that then check your http servers error log file. Chances are that you operate a very old version of the apache http server, you may have to replace the [END] flag with the [L] flag which probably will work just fine in this scenario.
And a general hint: you should always prefer to place such rules inside the http servers (virtual) host configuration instead of using dynamic configuration files (.htaccess style files). Those files are notoriously error prone, hard to debug and they really slow down the server. They are only supported as a last option for situations where you do not have control over the host configuration (read: really cheap hosting service providers) or if you have an application that relies on writing its own rewrite rules (which is an obvious security nightmare).
UPDATE:
Based on your many questions in the comments below (we see again how important it is to be precise in the question itself ;-) ) I add this variant implementing a different handling of path components:
RewriteEngine on
RewriteCond %{QUERY_STRING} (?:^|&)public_url=([^&]+)(?:$|&)
RewriteRule ^/?app/process\.php$ /api/%1 [R=301,QSD]
RewriteRule ^/?api/([^/]+)/?$ /app/process.php?public_url=$1 [END]
I am trying to get .htaccess to make the URL like this: example.com/app/api/acbd1234.
You don't do this in .htaccess. You change the URL in your application and then rewrite the new URL to the actual/old URL. (You only need to redirect this, if the old URLs have been indexed by search engines - but you need to watch for redirect loops.)
So, change the URL in your application to /app/api/acbd1234 and then rewrite this in .htaccess (which I assume in in your /app subdirectory). For example:
RewriteEngine On
# Rewrite new URL back to old
RewriteRule ^api/([^/]+)$ process.php?public_url=$1 [L]
You included a trailing slash in your earlier directive, but you omitted this in your example URL, so I've omitted it here also.
If you then need to also redirect the old URL for the sake of SEO, then you can implement a redirect before the internal rewrite:
RewriteEngine On
# Redirect old URL to new (if request by search engines or external links)
RewriteCond %{ENV:REDIRECT_STATUS} ^$
RewriteCond %{QUERY_STRING} (?:^|&)public_url=([^&]+)(?:$|&)
RewriteRule ^process\.php$ /app/api/%1? [R=302,L]
# Rewrite new URL back to old
RewriteRule ^api/([^/]+)$ process.php?public_url=$1 [L]
The check against REDIRECT_STATUS is to avoid a rewrite loop. ?: inside the parenthesised subpattern avoids the group being captured as a backreference.
Change the 302 (temporary) to 301 (permanent) only when you are sure it's working OK, to avoid erroneous redirects being cached by the browser.
I want to make a proxy for external links with apache's mod_rewrite module.
I want it to redirect user from, ie http://stackoverflow.com/go/http://example.com/ to http://example.com/ where http://stackoverflow.com/ is my site's URL. So I added a rule to .htaccess file.
RewriteRule ^/go/http://(.+) http://$1 [R=302,L]
But it doesn't work at all. How to fix this?
I am not sure if Apache or the browser reduces // to /, but since it doesn't change the directory one of them reduces this to a single slash on my setup. That's why the second slash has a ? behind it in the rule below:
RewriteRule ^go/http://?(.*)$ http://$1 [R,L]
This will redirect the user to that domain.
This will rewrite all urls (without the beginning http://) to new complete URL. If you're gonna use https links also, you need something like the second rule.
RewriteRule ^go/(.*) http://$1 [R=302,L,QSA,NE]
RewriteRule ^gos/(.*) https://$1 [R=302,L,QSA,NE]
I also added the QSA if your need to include parameters
I have the following re-write rule which directs krmmalik.com to krmmalik.com/me
How do i make sure this rule is a 301 re-direct, and if it isnt one already, how can i turn it into one?
I've tried using the mixing and matching the tips from this site
http://www.webweaver.nu/html-tips/web-redirection.shtml
as well as Google's Support Articles and existing SO questions, but not having much luck. Note the re-write rule in itself so far has been working fine.
I've also added a CNAME for "www" to "krmmalik.com" in my DNS file. Is that good enough, or do i need to add a specific 301 redirect for that as well?
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{HTTP_HOST} ^(www.)?krmmalik.com$
RewriteRule ^(/)?$ me [L]
Try the following:
RewriteRule ^/?$ /me [L,R=permanent]
The R=permanent flag instructs a 301 status redirect (and you can use R=301 if you prefer, but I think that "permanent" is more readable).
Putting a forward-slash at the start of the /me target URL will tell Apache to redirect the user to the directory named "me" at the web server's public root directory. So in your case it should redirect the user to krmmalik.com/me (or www.krmmalik.com/me).
Also, you don't need to wrap the match pattern in parentheses, because you don't need to capture the slash for later use. So ^/?$ will do the job fine.
I'm working on a website where I want the url
www.example.com/directory1/states/california.php
to point to
www.example.com/directory1/california
And a similar url change for the city pages as well:
www.example.com/directory1/cities/miami.php
should point to
www.example.com/directory1/miami
I'm using the following rules in my access file to change the url:
RewriteRule ^directory1/(alabama|alaska|arizona|arkansas|california|colorado|connecticut|delaware|florida|georgia|guam|hawaii|idaho|illinois|indiana|iowa|kansas|kentucky|louisiana|maine|maryland|massachusetts|michigan|minnesota|mississippi|missouri|montana|nationwide|nebraska|nevada|new_hampshire|new_jersey|new_mexico|new_york|north_carolina|north_dakota|ohio|oklahoma|oregon|pennsylvania|rhode_island|south_carolina|south_dakota|tennesee|texas|us_virgin_islands|utah|vermont|virginia|washington|west_virigina|wisconsin|wyoming)$ /directory1/states/$1.php [L]
RewriteRule ^directory1/(.*)$ /directory1/cities/$1.php [L]
However, nothing changes in the url bar and I always get a 404 not found. When I tested it with the htaccess checker, the output url is always correct. What is wrong with my rules? Is there a way to test how/if mod_rewrite is even functioning?
Some server configs require you to turn the rewrite engine on in your .htaccess file. Right at the top:
RewriteEngine on
I've also known some server configs where the file path starts/ends with a / (due to other rewrite rules already being run on the request) so perhaps allow for that to be there in the rules:
RewriteRule ^/?directory1/(alabama|alaska|arizona|arkansas|california|colorado|connecticut|delaware|florida|georgia|guam|hawaii|idaho|illinois|indiana|iowa|kansas|kentucky|louisiana|maine|maryland|massachusetts|michigan|minnesota|mississippi|missouri|montana|nationwide|nebraska|nevada|new_hampshire|new_jersey|new_mexico|new_york|north_carolina|north_dakota|ohio|oklahoma|oregon|pennsylvania|rhode_island|south_carolina|south_dakota|tennesee|texas|us_virgin_islands|utah|vermont|virginia|washington|west_virigina|wisconsin|wyoming)/?$ /directory1/states/$1.php [L]
RewriteRule ^/?directory1/(.*)/?$ /directory1/cities/$1.php [L]
I have this old survey link that is has been superseded by another link, so basically I want anyone trying to access the URL:
http://mywebsite.com/survey/view_survey.php?surveyID=1
To be redirected to:
http://mywebsite.com/survey/view_survey.php?surveyID=2
Can I do this in the Apache configuration or htaccess file?
I tried the following rule in the Redirect section of my httpd.conf file:
Redirect 301 /survey/view_survey.php?surveyID=1 http://mywebsite.com/survey/view_survey.php?surveyID=2
But it doesn't work. I am suspecting that the GET parameters are not used when processing the rule.
Is my only option to hack my code to redirect on a specific surveyID?
Following the suggestion of using the Rewrite rules, I tried the following in my .htaccess file:
RewriteRule ^survey/view_survey\.php\?surveyID=1525$ /survey/view_survey.php?sur
veyID=1607
But that doesn't work. I do have the rewrite engine up and running, because I have another rewrite rule currently running.
Try this in a .htaccess file:
RewriteEngine on
RewriteCond %{QUERY_STRING} (^|.*&)surveyID=1525(&.*|$)
RewriteRule ^survey/view_survey\.php$ /survey/view_survey.php?%1surveyID=1607%2 [L,R=301]
RewriteEngine On
RewriteCond %{QUERY_STRING} ^surveyID=1525$
RewriteRule ^/survey/view_survey\.php /survey/view_survey.php?surveyID=1607 [R=301]
Check out the QSA portion of the mod_rewrite.
It does GET string manipulation.
