$_GET url

[taigaa]

Hi, can you help me with one issue? I need to replace some elements on my site by an external service. But the CMS automaticly redirects urls like:
http://www.example.com/?ym_phone=show&ym...m_v0=12345

to the main page. So the script of those service does nothing. What can I do with it?

Every url with a slug beginning with "?" symbol redirects to the main page.

Is it wrong htaccess syntax or a limitation of the cms engine?

Have you enabled canonical redirects (GSCANONICAL setting) in gsconfig?

[shawn_a]

? is a querystring

so your url is essentially

webroot_default_index?querystring.
or index.php?querystring

You will have to have a special rewrite or redirect, so that those querystrings goto a new page.
Or change the links to use an actual file, not an empty one.
