This:

rewriterule test index.php
.works. This:
rewriteengine on
rewriterule index.php index.php
.works.
But this:
rewriteengine on
rewriterule index.php /index.php
.gives me 500 internal server error.
How is it that index.php index.php works, yet index.php /index.php doesn't?
What's causing this error?
Because you asked for the WHY I will share some insights on it.
For this rewriterule index.php index.php instruction Apache recognize that the origin and the destination is the same initial URL equal rewritten URL and therefor [IGNORING REWRITE]
The second one is not 100% the same so Apache try to execute it. But because the slash makes not really any differences we rewrite index.php to /index.php and after each rewrite Apache checks all rewrite instructions for the new destination again, and now we end up in an infinite rewrite loop.
Just set the log level LogLevel alert rewrite:trace3 in your configuration and you can see it your self.

I'm trying to direct all traffic to the homepage only to a php script called go.php that gets a variable from the URL.
If someone visits domain.com/username go.php gets the username, looks up their information, saves the information to a session and then redirects to index.php and displays a modified version of the homepage (same domain) that has the retrieved information. Everything works except the mod rewrite part.
I tried the following and am not sure what I am doing wrong:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteRule ^/$ go.php?id=$1 [QSA]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
My logic was that if a request is to index.php it should be allowed, to prevent looping.
If the request is to the homepage it will go to go.php?id=username and the that script will redirect to index.php and trigger the prior mod rewrite rule to prevent looping.
Otherwise, it will do the regular redirect to index.php if the directory or filename doesn't exist.
Any thoughts on how to fix this?
I think this is what you mean:
RewriteRule ^(.*)$ go.php?id=$1 [QSA]
Explanation:
I'm looking at the ^/$ in the regular expression in the go.php rewrite rule. I've tested that and it appears to be an impossible match in that situation. One might be wanting to capture requests for root. But the forward slash is not passed to this portion of the RewriteRule for root. so a call for root (only) is ^$. And there's also no capturing parenthesis to feed the $1 you have appended to go.php?id=$1.
If none of my RewriteRule [L] matches, I want to redirect to a nice url /you/shall/not/pass, but show contents of /index.html.
This is what I am doing now (this is the very last rule in the file):
RewriteCond %{REQUEST_FILENAME} !-f # is not file
RewriteCond %{REQUEST_FILENAME} !-d # is not directory
RewriteCond %{ENV:REDIRECT_STATUS} !=200 # wasn't already redirected
RewriteRule .* index.html
It works fine, but keeps whatever garbage was written in the URL. I want it to be changed.
Doing this didn't work
#RewriteCond same as above
RewriteRule .* /you/shall/not/pass [R]
RewriteRule ^/you/shall/not/pass index.html
I apparentely don't understand how [R] works, whether it continues forwarding the changed url to other RewriteRules or not and what page it redirects to when the end of file is reached.
You can use ErrorDocument 404 with a rewrite rule for this:
Options +FollowSymLinks
ErrorDocument 404 http://domain.com/you/shall/not/pass
Then create a symbolic link like this:
/public_html/you/shall/not/pass -> /public_html/index.html
Replace /public_html/ with your DocumentRoot path.
So, after countless hours I made it work, somehow, I guess...
I am too tired to investigate, but I will get back later and edit if it is wrong.
ErrorDocument 404 http://domain.com/you/shall/not/pass # redirects if document does not exist
RewriteEngine on
RewriteRule ^$ /you/shall/not/pass [L,R] # redirects if request URI is empty, skips rest
RewriteRule ^you/shall/not/pass$ /index.html [L] # puts different resource to matched url
It's kinda weird that the solution is that short.. How come I didn't try that already?
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteRule ^$ public/ [L]
RewriteRule (.*) public/$1 [L]
</IfModule>
I'm using wamp apache on windows 7. mod_rewrite.so has been enabled in httpd.conf. This code was directly taken from a tutorial found here: http://anantgarg.com/2009/03/13/write-your-own-php-mvc-framework-part-1/
It's purpose is to redirect calls to the ./public folder where the actual logic lies.
I get an internal server error (http 500) when I try to browse index.php in the directory of this .htaccess file. When I remove the two rewriterule statements, it works.
Not sure why, but no error shows up in the logs folder. There is no error log whatsoever.
Any clue on what's going wrong here?
Your expression, (.*), matches the target, /public/something. The rewrite engine loops until the request URI stops getting changed, and your request URI is turning into /public/public/public/public/public etc because there's nothing that stops the rewriting process. Try adding a condition to prevent the loop:
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteRule ^$ public/ [L]
RewriteCond %{REQUEST_URI} !^/public/
RewriteRule (.*) public/$1 [L]
</IfModule>
So if the request already starts with /public, don't apply the rule.
I'm using this rewriterule:
RewriteRule ^page/([^/]*)$ http://example.com/page?q=$1 [QSA,L]
If I go to example.com/page/somePage I get redirected to example.com/page?q=somePage
But I don't want a redirection, what I want is the URL to always be example.com/page/somePage
How to do this?
Thank you
I removed http://example.com but it doesn't work, I get Page not Found.
I am using Wordpress for my site, this is my complete .htaccess:
RewriteEngine On
RewriteBase /
RewriteRule ^page/([^/]+)/?$ page?q=$1 [L]
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
Whenever you specify the http:// at the beginning of the path to be rewritten to, Apache will always force a 301 redirect to the new URL, whether the URL is on the same website or not. Simply removing the http://example.com part should fix your problem.
As for the page not found, is there another RewriteRule somewhere that tells just 'page' to be processed as 'page.php' or something of the sort? Do you have your PHP files saved without extensions?
Well then your problem is you definitely need to remove the [L] flag because you're telling Apache not to process any more RewriteRules for that request, so it never looks at the WordPress rewrites because that rule was already executed and Apache was told that should be the final rule. I would recommend leaving the [QSA] in the line though, that would not affect the overall outcome of your script.
i have the following .htaccess
RewriteEngine On
RewriteRule ^([a-zA-Z0-9_-]+)/$ index.php?type=Navigation&action=$1
RewriteRule ^([a-zA-Z0-9_-]+)$ index.php?type=Navigation&action=$1
Options All -Indexes
which sends everything to index.php in the root folder. But in my structure i have something like
/root
/.htaccess
/index.php
/files
/intranet
i was wondering if there is a RewriteRule exception so that when i type www.mysite.com/intranet it goes to the 'intranet' folder without passing trough the index.php file
thanks!
Yes. I believe you just put a rule before the others with the url you do not want rewritten, and specify that it shouldn't be rewritten using - like so:
RewriteRule ^intranet/.*$ - [L]
RewriteCond %{REQUEST_URI} ^\/intranet\/?
RewriteRule ^([a-zA-Z0-9_-]+)\/?$ index.php?type=Navigation&action=$1 [L]
Will do the trick.
