.htacceess mod rewrite

Just doing some mod rewrite stuff and am having a problem with the last bit, trying to get the URL created by the form get method to redirect to the type of URLs I want. Problem is I am getting 500 Internal server error.

RewriteRule ^random-integer/$ /integer.php
RewriteRule ^random-integer/number-([0-9]+)-minimum-([0-9]+)-maximum-([0-9]+)-unique-(yes|no).html$ /integer.php?num=$1&min=$2&max=$3&u=$4
RewriteRule ^random-integer/(.+)$ /random-integer/ [R=301]
RewriteRule ^random-integer$ /random-integer/ [R=301]

#Below code is causing problem
RewriteCond %{QUERY_STRING} ^?num=([0-9]+)&min=([0-9]+)&max=([0-9]+)&u=(yes|no)$
RewriteRule ^random-integer/$ /random-integer/number-%1-minimum-%2-maximum-%3-unique-%4.html [R=301]

on the last rule why are you using %1 %2 etc instead of $1, $2

 

[Dean]

I thought you are meant to use %1 isntead of $1 for the query string values? Tryed it the other way to and it didnt work so dont think that is the problem.

I think the first question mark in the RewriteCond line is wrong. The question mark is not part of the query string - it separates the query string from the rest of the URI. You probably want:

RewriteCond %{QUERY_STRING} ^num=([0-9]+)&min=([0-9]+)&max=([0-9]+)&u=(yes|no)$

You might want to consider adding some "L" flags to speed up rewrite rule processing.

The ? was causing the error but I still couldn't get it to do what I actually wanted. I escaped & and = signs, not sure if this was needed, but what finally got it to work was putting it ahead of the other rewrite rules.

Just another question, I added [L] to the end of all the rewrite rules and there seems to be no problem but when should I use and not use this?

The L flag makes mod_rewrite stop processing further rules. Use it if you don't want multiple rewrite rules to apply to the same URL.

Redirects cause a new URL to be requested, therefore the rules will be executed again.
