Question

Hello I have been searching the web for an answer to this but I can not find it. I am looking to use htaccess to strip a specific parameter from the url.

For example, I have the following urls:

www.mysite.com/product.php?product_id=123&session=sdfs98d7fs9f8d7
www.mysite.com/anotherurl.php?session=12312341341&someotherparam=123

I would need them to 301 redirect to:

www.mysite.com/product.php?product_id=123
www.mysite.com/anotherurl.php?someotherparam=123

Note the urls above are just examples. Ill need the session param removed from any and all urls no matter how many params are part of the url or where session is located.

I think I need a way to the url string up to session=blah and the url string after session=blah, then combine both parts and redirect to the new url.

Any help is greatly appreciated, thanks.

I found a solution on another site

# case: leading and trailing parameters
RewriteCond %{QUERY_STRING} ^(.+)&session=[0-9a-z]+&(.+)$ [NC]
RewriteRule (.*) /$1?%1&%2 [R=301,L]

# case: leading-only, trailing-only or no additional parameters
RewriteCond %{QUERY_STRING} ^(.+)&session=[0-9a-z]+$|^osCsid=[0-9a-z]+&?(.*)$ [NC]
RewriteRule (.*) /$1?%1 [R=301,L]
