I'm learning how to mod rewrite URLs and I encountered a 500 server error after having this .htaccess file in my root folder:
RewriteEngine On
RewriteRule ^([^/]*)$ /a.php?a=$1 [L]
It would be great if someone can tell me which part I got wrong, thanks
Include at least all basic directives and one condition to prevent loops. Like this:
Options +FollowSymlinks
RewriteEngine On
RewriteBase /
# Prevent loops
RewriteCond %{REQUEST_URI} !a\.php [NC]
RewriteRule ^([^/]*)/? a.php?a=$1 [L]
Maybe that's what you need, although I did not test it because it is impossible without a sample of the incoming URL, which is missing in the question.

My main domain is smile.ws
I have installed yourls in smile.ws/yourls.
As a result, all my shortened urls are smile.ws/yourls/link instead of smile.ws/link
I followed the wiki instructions but that didn’t help.
I looked around and found a plugin called "Swap Short Url" which is supposed to help in these situations. It has slightly different .htaccess recommendation. I followed the instructions correctly and it works, because now the urls are smile.ws/link. But when you click on them, you get a 404 error.
How can I fix this? Thanks!
PS I know this is not a programming question. However, Stackoverflow has a tag for YoURLS that has 55 questions.
This to me sounds like it is related to the web servers .htaccess file but I can't be certain unless you can give us an example. I have a YOURLS site that work as you are describing without using a plugin. This really comes down to how the web server is configured and the YOURLS settings. Here is a sample of my .htaccess file.
# BEGIN YOURLS
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^.*$ /yourls-loader.php [L]
</IfModule>
# END YOURLS
In your config file this line needs to look like this.
define( 'YOURLS_SITE', 'http://smile.ws' );
If this doesn't work it might be due to your web server not having the correct permissions set or the rewrite module not enabled assuming you are using apache.
Did anyone check the root .htaccess?
# BEGIN YOURLS
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^.*$ /YOURLS/yourls-loader.php [L]
</IfModule>
# END YOURLS
This line needs to set the subdirectory /your dir here/
RewriteRule ^.*$ /YOURLS/yourls-loader.php [L]
On my CodeIgniter site, I would like to add a specific rewrite rule, so that this url
http://www.exemple.com/cache.manifest
would rewrite to
http://www.exemple.com/controller/manifest
(because Safari 7 seems to only accept .manifest files for ApplicationCache)
So I try to add this line to my htaccess
RewriteRule ^cache.manifest$ controller/manifest
I added it before the other rewrite rules :
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule ^cache.manifest$ controller/manifest
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php/$1 [L]
</IfModule>
But it returns a 404. If I change the line to
RewriteRule ^cache.manifest$ test.html
it works. So the first part on my rule is correct.
If I try to access directly to www.example.com/controller/manifest, it works to, so my url is correct.
I tried also
RewriteRule ^cache.manifest$ index.php/controller/manifest [L]
But it doesn't work either…
Any clue ?
Thanks a lot
I tried some tests on my local server and I think the following might work:
RewriteRule ^cache.manifest$ /index.php/controller/manifest [R,L]
I am not entirely sure if you need the leading "/" or "/index.php", so you
may need to experiment.
You need the [R] flag to force a redirect. In this situation, you want Apache
to look for the string cache.manifest in the URL, and then go to the CI page
controller/manifest.
It appears that you need to explicitly set the redirect.
Please let me know if this works. Good luck!
My goal is to rewrite
http://domain.com/subdir/index.php?p=page-title
as
http://domain.com/subdir/page-title
The code below looks right, but I get a 404 Not Found?
RewriteEngine on
RewriteRule ^/subdir/([^/.]+)/?$ /subdir/index.php?p=$1 [L]
Please, remove the leading slash from your rule (assuming it's in .htaccess instead of httpd.conf)
RewriteEngine on
RewriteRule ^subdir/([^/.]+)/?$ /subdir/index.php?p=$1 [NC,QSA,L]
I have a .htaccess that is supposed to rewrite my URL. My host has told me that it supports URL rewriting, and I verified that by using phpinfo() and checking.
Anyways, this is my .htaccess:
RewriteEngine On
RewriteRule ^([_a-zA-Z0-9]+)$ index.php?page=$1 [R]
It works like a charm in local, but on my server, it doesn't do anything.
I checked this before on the internet and some people had it, but they all had a 404 error, while I don't have a 404 error. It simply doesn't redirect, it doesn't do anything, so I get all kind of error messages.
RewriteRule ^([_a-zA-Z0-9]+)$ index.php?page=$1 [R]
The regex in your rule doesn't match strings with slashes at any position. I am not sure that's acceptable and you don't give any request examples, but I don't think it is.
You may try this rule-set in one .htaccess file at root directory:
Options +FollowSymlinks -MultiViews
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_URI} !index\.php [NC]
RewriteRule ^([^/]+)/?$ index.php?page=$1 [L]
For permanent redirection replace [L] with [R=301,L].
You can make sure that the file (!-f) or directory (!-d) that you're matching doesn't exist before the rewrite. That way you don't end up with a 500 loop with something like /index.php?page=index. Additionally the ^ character is matching the beginning of the string, so if your original test was in a subdirectory it would not rewrite since you weren't allowing slashes.
This should work for any instance, however it will ONLY make the page variable the last string in the URI.
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ([_a-zA-Z0-9]+)$ /index.php?page=$1 [R,L]
I can't seem to get past a Bad Request error while setting up mod_rewrite. I've been trying for a while, so here's what I have.
The url I'm trying to access is:
gordons.local/brewCalc
The page I'd like to see is
gordons.local/index.php?page=brewCalc
Here's my rewrite rule:
RewriteEngine on
RewriteLog /var/www/gordons.com/logs/rewrite.log
RewriteRule ([^/]+)/?$ index.php?page=$1 [L]
I've used a regex tool, and this tool, but no matter what I end up with a page that says:
Bad Request
Your browser sent a request that this server could not understand.
Additionally, a 400 Bad Request error was encountered while trying to use an ErrorDocument to handle the request.
Apache/2.2.12 (Ubuntu) Server at gordons.local Port 80
Also, I'm not getting any information in my access, error or rewrite logs.
EDIT: My rewrite rules are in my vhost file. (/etc/apache2/sites-available/gordons.local)
In case anybody ever finds themselves here, my issue was a missing leading slash before the replacement.
RewriteRule ([^/]+)/?$ index.php?page=$1 [L]
Should have been
RewriteRule ([^/]+)/?$ /index.php?page=$1 [L]
Grrrr....
If you see Apache's error.log you would be able to see the actual error. Most likely you are trying to put above rules in .htaccess file and RewriteLog is not allowed in .htaccess file. Also your RewriteRule will redirect more than you intend. So if you comment out your RewriteLog and have your RewriteRule like this then it should work:
RewriteEngine On
RewriteBase /
# request is not for a file
RewriteCond %{REQUEST_FILENAME} !-f
# request is not for a directory
RewriteCond %{REQUEST_FILENAME} !-d
# forward to index.php
RewriteRule ^([^/]+)/?$ index.php?page=$1 [L,QSA,NC,NE]
NC - Ignore case comparison
NE - Do not encode RHS URI
QSA - Append existing Query String into new one
L - Mark it last rule
