I have wasted an entire morning trying to do something very simple.
I have a local server set up with WampServer. The rewrite module is ON in httpd.conf. I want to have something like
http://localhost/wordpress/assets/whatever.jpg`
point to
http://localhost/wordpress/assets/test/whatever.jpg`.
I have tried so many variations it is stupid, and I either get no effect, or a redirect loop, or a server error or a message saying that the file can't be found at a location I don't want it to be found at. How about this version, why doesn't this work?
RewriteEngine on
RewriteBase /wordpress/assets/
RewriteRule (.*) test/$1
It causes an internal server error. This one gets pretty close, it gets to the test directory but not the jpg:
RewriteRule . test/
EDIT: oh, I meant to say that this .htaccess file is in the assets folder. I tried things higher up as well. I thought rewriting wasn't happening at all until I figured out the RewriteBase thing.
You need to make sure you're not already rewrite the test folder. The rewrite engine loops so the second time around it'll get rewritten again. So something like:
RewriteEngine on
RewriteBase /wordpress/assets/
RewriteCond $1 !^test/
RewriteRule (.*) test/$1
or
RewriteEngine on
RewriteBase /wordpress/assets/
RewriteCond %{DOCUMENT_ROOT}/wordpress/assets/test/$1 -f
RewriteRule (.*) test/$1

I've never been good at .htaccess, I'm trying to copy and paste some code that worked on another one of my domains and modify it to work here. I will have several rewritten URLs, some static, some dynamic, but I can't even get the simplest of them to work. This one is testable here: http://lindseymotors.com/home
Clearly, index.php is available because if you access http://lindseymotors.com it works.
RewriteEngine On
RewriteCond %{HTTP_HOST} ^.* [NC]
RewriteRule ^home$ index.php
RewriteRule ^home/$ index.php
# When answering, if you could write a statement that would combine
# both of the statements above into one that would be appreciated.
As I said, these same conditions worked on another one my domains because I copied the code right over. I asked my server admin to double check everything on his end and it was fine. Any ideas?
Only thing I can think of is make sure the use of .htaccess is really on. The easiest way you can check since your server admin says it's fine is to put random text at the top of your .htaccess file. If your .htaccess file is being read and .htaccess files are enabled, it should throw a 500 internal server error. If not, then they don't have .htaccess files enabled and need to add AllowOverride All to the Apache config vhost.
Here is your rule combined into one as you noted. You really don't need the RewriteCond, but I will leave since you were using it previously.
RewriteEngine On
RewriteCond %{HTTP_HOST} ^.* [NC]
RewriteRule ^home/?$ index.php [L]
I have been pulling my air out over this. It worked before the server migration!
Ok so basically it's as simple as this:
I have a .php file that I want to view the content of using a SEO friendly URL via a ReWrite rule.
Also to canonicalise and to prevent duplicate content I want to 301 the .php version to the SEO friendly version.
This is what I used and has always worked till now on the new server:
RewriteRule ^friendly-url/$ friendly-url.php [L,NC]
RewriteRule ^friendly-url.php$ /friendly-url/$1 [R=301,L]
However disaster has struck and now it causes a redirect loop.
Logically I can only assume that in this version of Apache it is tripping up as it's seeing that the script being run is the .php version and so it tries the redirect again.
How can I re-work this to make it work? Or is there a config I need to switch in WHM?
Thanks!!
This is how your .htaccess should look like:
Options +FollowSymLinks -MultiViews
RewriteEngine On
RewriteBase /
# To externally redirect /friendly-url.php to /friendly-url/
RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s/+(friendly-url)\.php [NC]
RewriteRule ^ /%1/? [R=302,L]
## To internally redirect /anything/ to /anything.php
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{DOCUMENT_ROOT}/$1\.php -f
RewriteRule ^(.+?)/$ $1.php [L]
Note how I am using R=302, because I don't want the rule to cache on my browser until I confirm its working as expected, then, once I can confirm its working as expected I switch from R=302 to R=301.
Keep in mind you may have also been cached from previous attempts since you're using R=301, so you better of trying to access it from a different browser you have used just to make sure its working.
However disaster has struck and now it causes a redirect loop.
It causes a redirect loop because your redirecting it to itself, the different on my code is that I capture the request, and redirect the php files from there to make it friendly and then use the internal redirect.
The exact same .htaccess file will work differently depending on where it's placed because the [L]ast flag means something different depending on location. In ...conf, [L]ast means all finished processing so get out, but in .htaccess the exact same [L]ast flag means start all over at the top of this file.
To work as expected when moving a block of code from ...conf to .htaccess, most .htaccess files will need one or the other of these tweaks:
Change the [L]ast flags to [END]. (Problem is, the [END] flag is only available in newer [version 2.3.9 and later] Apaches, and won't even "fall back" in earlier versions.)
Add boilerplate code like this at the top of each of your .htaccess files:
*
RewriteCond %{ENV:REDIRECT_STATUS} !^[\s/]*$
RewriteRule ^ - [L]
This problem has been bugging me for a while now.
I have a created a small site engine and I'm using mod_rewrite to tell the engine what page to proccess, SEO friendly links is a bonus :).
This is how it's works today:
the adress http://www.example.com/site/page
becomes http://www.example.com/engine.php?address=page
But what i want is:
the adress http://www.example.com/page
becomes http://www.example.com/engine.php?address=page
Everything works fine if i create a psuedo directory for the calls (/site) but when i try to do the same from the root strange things start to happends.
RewriteBase /
RewriteRule ^site/(.*) engine.php?%{QUERY_STRING}&address=$1
Works fine: /site/about/contacts becomes eninge.php?address=about/contacts
RewriteBase /
RewriteRule ^(.*)$ eninge.php?%{QUERY_STRING}&address=$1
Doesn't work, for some reason /about/contacts becomes eninge.php?address=eninge.php
(.*) means catch anything. Have you tried exluding files and directory before your catch-all ? Because it will cause an infinite recursion without it.
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ eninge.php?%{QUERY_STRING}&address=$1 [L]
More information is available in the official documentation: http://httpd.apache.org/docs/current/mod/mod_rewrite.html
Update: You should also specify [L] at the end of your rule, to tell Apache to end the rewriting process here.
Check the RewriteLog (this has been updated in 2.4, check current docs if not using 2.2):
RewriteLog "/usr/local/var/apache/logs/rewrite.log"
RewriteLogLevel 3
This will show you exactly what mod_rewrite is doing and allow you to tune your configuration based on its output. Beware - it grows very quickly, and should never be used in production environments.
As an aside, you have some typos in your post - worth verifying that these differ from your config.
RewriteCond %{REQUEST_FILENAME} !^engine.php
RewriteRule (.*) engine.php?address=$1 [QSA,L]
Try this. What you have is causing the rewrite to loop around and first do engine.php?address=about/contacts as you were expecting, but then go around again and rewrite that to engine.php?address=engine.php. Make sense? The [QSA,L] is a Query String Append and Last flag that will add the query string to your URL and tell the rewrite engine to stop looking for rewrites. The RewriteCond %{REQUEST_FILENAME} !^engine.php is to check that you haven't already specified the engine rewrite by ensuring the current URL doesn't start with engine.php. This is necessary if you are writing this in an .htaccess file rather than the .httpd config files.
I basically want each request to
http://localhost/~lucamatteis/datadict/AccessionMainName
to actually call
http://localhost/~lucamatteis/datadict/index.php/AccessionMainName
Here's my current .htaccess physically located under ~lucamatteis/datadict/
RewriteEngine on
RewriteBase /~lucamatteis/datadict/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]
But unfortunately this doesn't work. I've tried everything. At this point I think the issue is that It's using the tilde, or I'm not sure.
In the phpinfo() under the loaded modules section mod_rewrite is loaded. I'm not sure where else to look as I might need to load an extra thing for mod_rewrite to work.
Any ideas?
First of all make sure that you're able to override Apache configuration trough .htaccess file ( AllowOwerride config directive).
Then try to remove RewriteBase directive totally. In this case the current directory will be used as base.
Change you ReWriteBase to your physical directory:
/home/lucamatteis/public_html/datadict (or something similar)
http://httpd.apache.org/docs/1.3/mod/mod_rewrite.html#RewriteBase
I think the problem is that you want to do an internal redirection to a file that does not exists:
/home/lucamatteis/public_html/datadict/index.php/AccessionMainName
This will only work if index.php is a directory and AccessionMainName is a file.
I don't think such thing can be done. Most of the times, using query string parameters is all you need:
index.php?AccessionMainName
... and you read it from $_GET['AccessionMainName'].
I only recently found out about URL rewriting, so I've still got a lot to learn.
While following the Easy Mod Rewrite tutorial, the results of one of their examples is really confusing me.
RewriteBase /
RewriteRule (.*) index.php?page=$1 [QSA,L]
Rewrites /home as /index.php?page=index.php&page=home.
I thought the duplicates might have had been caused by something in my host's configs, but a clean install of XAMPP does the same.
So, does anyone know why this seems to parse twice?
And, to me this seems like, if it's going to do this, it would be an infinite loop -- why does it stop at 2 cycles?
From Example 1 on this page, which is part of the tutorial linked in your question:
Assume you are using a CMS system that rewrites requests for everything to a single index.php script.
RewriteRule ^(.*)$ index.php?PAGE=$1 [L,QSA]
Yet every time you run that, regardless of which file you request, the PAGE variable always contains "index.php".
Why? You will end up doing two rewrites. Firstly, you request test.php. This gets rewritten to index.php?PAGE=test.php. A second request is now made for index.php?PAGE=test.php. This still matches your rewrite pattern, and in turn gets rewritten to index.php?PAGE=index.php.
One solution would be to add a RewriteCond that checks if the file is already "index.php". A better solution that also allows you to keep images and CSS files in the same directory is to use a RewriteCond that checks if the file exists, using -f.

From the Apache Module mod_rewrite documentation:
'last|L' (last rule)
[…] if the RewriteRule generates an internal redirect […] this will reinject the request and will cause processing to be repeated starting from the first RewriteRule.
To prevent this you could either use an additional RewriteCond directive:
RewriteCond %{REQUEST_URI} !^/index\.php$
RewriteRule (.*) index.php?page=$1 [QSA,L]
Or you alter the pattern to not match index.php and use the REQUEST_URI variable, either in the redirect or later in PHP ($_SERVER['REQUEST_URI']).
RewriteRule !^index\.php$ index.php?page=%{REQUEST_URI} [QSA,L]
