问题
I have a .htaccess file that is using Mod_Rewrite but I am running into a problem if someone puts in junk in the URL it generates a 500 error, and displays all my mod information. I would like to either stop it from generating the 500 error or forward that error to a different page. I have tried.
Error Document 500 /index.php
...but it does not work or redirect.
Here is my full .htaccess
Options -Indexes
Options +FollowSymlinks
ErrorDocument 500 /index.php
RewriteEngine On
RewriteRule ^BEARS bears.php?page=bears [NC,L]
RewriteCond %{http_host} ^www.domian.org/login.php [NC]
RewriteRule ^(.*)$ https://www.domian.org/login.php [R=301,L]
RewriteCond %{http_host} ^domian.com [NC]
RewriteRule ^(.*)$ http://www.domian.org/$1 [R=301,L]
RewriteCond %{http_host} ^domian.org [NC]
RewriteRule ^(.*)$ http://www.domian.org/$1 [R=301,L]
RewriteCond %{http_host} ^www.domian.com [NC]
RewriteRule ^(.*)$ http://www.domian.org/$1 [R=301,L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.+)/DB/(.+)/page/(.+)$ $1.php?DB=$2&page=$3 [L,QSA]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.+)/DB/(.+)$ $1.php?DB=$2 [L,QSA]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.+)/(.+)$ $1.php?page=$2 [L,QSA]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.+)$ $1.php?page=$1 [L,QSA]
Also does anyone know where the 500 error is being generated from. I know the error folder has the error documents in there, but this error says "Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request" , and I cannot find where this is pulling from.

Where is this loop happening? Not seeing it.
回答1:
To expand on your answer, it is more specifically this line:
RewriteRule ^(.+)$ $1.php?page=$1 [L,QSA]
which does not check to see if the filename already ends with PHP.
It loops around, adding .php.php.php.php until the max is reached (check apache/logs/error.log) and then just serves the original page, which happens to be present, so it looks like everything's ok.
To fix this, add something like this:
RewriteRule ^(.*)\.php$ - [L]
which stops ([L]) if the address ends with .php.

I figured I would put the problem solution here just in case someone comes across the same issue.
My problem code was this snippet...
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.+)$ $1.php?page=$1 [L,QSA]
Seems that a junk entry will cause this too loop like crazy.
