301 redirect of a dynamic URL using mod rewrite problem with passed on

[finkedelic]

Hi there,

I have a bit of challenge with redirecting a dynamic URL.
I am trying to redirect a URL to another URL but the resulting URL has the query string of the original URL added to it and I don't want that. Can't seem to find a solution anywhere...

Original URL: http://www.domain.com/CMS/index.php?Itemid=1
Target URL: http://www.domain.com

Code used in .htaccess:

RewriteEngine On
RewriteCond %{QUERY_STRING} Itemid=1
RewriteRule ^.*$ http://www.domain.com [R=301,L]

Resulting URL: http://www.domain.com/Itemid=1

Desired resulting URL: http://www.domain.com

Anyone any ideas?
Thanks!

The answer to this question is posted almost every day in this forum.

Indeed there have been five threads in the last week with the answer.

You need a question mark to clear the query string.


Note. As you have used the .* pattern in your code you are not restricting it to redirect only requests containing

CMS/index.php

. Is that what you want? I would replace the .* with something like ^CMS/ with no end anchor.

Hi g1smd,

thanks. I read about the question mark in other posts but it's not clear to me where to place the question mark. Hence, I thought this was a different situation...

Sorry, new to Apache...

So where should I put the question mark?

[g1smd]

On the end of the target URL, a question mark clears the query string data and stops it being appended to that new URL.


Use example.com in here to stop forum auto-linking.

Thank!

I now wrote it like this:

RewriteCond %{QUERY_STRING} Itemid=1
RewriteRule ^index.php [domain.com?...] [R=301,L]

Am I right if I explain the core of the above code like this (just checking if I am starting to get it):

If the original URL contains 'Itemid=1'
Then rewrite the URL to [domain.com,...] at least if it the original URL starts with 'index.php'

Thanks for helping out!

It reads:

If the requested path "begins" indexXphp (where X is "any" character - you should escape the period if you want to match "index DOT php") and the query string "contains" Itemid=1 (with no anchoring for ^ & $, it also matches SomeItemid=1 and Itemid=10002) then redirect to root URL of www subdomain stripping any parameters that were present.

The RewriteRule RegEx pattern is processed before the RewriteCond is looked at.

Always specify a trailing slash for the root URL of any domain or subdomain. Use example.com/ not example.com here.

That clears up a lot. Thanks!
