.htaccess how to cut away the parameter string

I want to redirect to a URL without parameter string

[jetteroheller]

From 1998 to 2000, I used a banner rotation system with a parameter string in the URL

http://www.example.com/target/page.htm?V=3&from=widget

Today, there are still visits of Googlebot with such parameter strings.

So I want something in my .htaccess to cut away all behind "?" or "&" or "#" and to redirect to the URL without the parameter string.

you could try this:

RewriteEngine on
Options +FollowSymLinks
RewriteCond %{QUERY_STRING} .
RewriteRule (.*) http://www.example.com/$1? [R=301,L]

[jdMorgan]

If only one page, or if only ".htm" pages have the query string attached, I'd suggest making the RewriteRule more specific, as this will eliminate unnecessary RewriteCond processing.

For example, to process .htm files only:

RewriteCond %{QUERY_STRING} .
RewriteRule ^([^.]+)[b]\.htm[/b]$ http://www.example.com/$1[b].htm[/b]? [R=301,L]

Or to process only the single page.htm file:

RewriteCond %{QUERY_STRING} .
RewriteRule ^[b]page\.htm[/b]$ http://www.example.com/$[b]page.htm[/b]? [R=301,L]

In fact, if any other pages on your site still use query strings, you will have to use a specific pattern to avoid stripping their query strings.

what he said!

i was assuming the most general case in my response.
avoid the ambiguous, greedy and promiscuous ".*" whenever possible.

Forgott, that I have Google AdSense search,
this creates in URLs like

/search.htm?domains=example.com&q=&sa=Google+Search

Now I have in my .htaccess

RewriteCond %{QUERY_STRING} ^B= [NC,OR]
RewriteCond %{QUERY_STRING} ^D= [NC,OR]
RewriteCond %{QUERY_STRING} ^N= [NC,OR]
RewriteCond %{QUERY_STRING} ^M= [NC,OR]
RewriteCond %{QUERY_STRING} ^S= [NC,OR]
RewriteCond %{QUERY_STRING} ^V= [NC,OR]
RewriteCond %{QUERY_STRING} ^i_mpg= [NC]
RewriteRule (.*) http://example.com/$1? [R=301,L]

But I can not figure out the Syntax of .htaccess

Instead of the list of forbidden string, I would like to allow only ond type of query string containing "domains=".

Something what would be in Perl

if ( index ( $QUERY_STRING ), "domains=" ) < 0 ) { cut away query sting and make 301 redirect }

[jdMorgan]

> query string containing "domains=".

# IF query string contains one or more characters
RewriteCond %{QUERY_STRING} .
# and IF query string does NOT contain "domains="
RewriteCond %{QUERY_STRING} !domains=
# THEN redirect to remove query string
RewriteRule (.*) http://example.com/$1? [R=301,L]
