Mod security resulted in 406 error

[DML]

Hey guys, please bear with me as I am new to php.

My hosting company recently installed mod_security on their servers.

I use a mod_rewrite on my website for SEF Url's. I am currently getting a 406 error on them. I emailed support and the response was:
Access denied with code 406. Pattern match "/../../ " at THE_REQUEST

From what I understand(very little), this means that my sef.php file is incorrectly coded in that I need to use the entire URL and not the shortcut(../).

Please advise, I have a campaign starting on Monday and all URL's that were previously indexed by search engines do not work. I don't have a clue on how to change this in the php file.

Much appreciated,

[Rob Holmes]

Mod_security is a serverhardening module for apache.

It has been known to break some sites.

If your hosting company can't support issues arising from their own actions I suggest they shouldn't have installed it.

Heres a helpful site with too many white papers for me to read through for you ;)

Hope this helps,

Thanks Rob

I read through the documentation, doesn't seem to help though. Removing multiple forward slash characters are in fact an anti-evasion technique in ModSecurity.

My problem is I don't know where to change this in my sef.php file in order to eliminate the slashes.

You will need to ask your host to create an exclusion entry for your site in their mod_security exclusion config files
