There has been a issue with the migration to IIS, where double slashes is automatically normalized (in rewrite) to a single slash.
This causes issues when using filtering in cgridview.
Will be seen as $_GET:
filter1 -> filter2
because the filtering it will show remove the empty value’s slash.
Is there any way to easily modify the way it makes the url, so I want to let it use a query string of ‘?filter1=&filter=22’.
If there is a know fix for IIS I would love to hear about it, or PHP in that case.
