I have following htaccess rules in the folder example.com/folder/index.php
RewriteEngine On
RewriteRule ^(.*)-filter-(.*)\.html$ $1.php?filter=$2
RewriteRule ^(.*)\.html$ $1.php
So the URL is rewritten to: example.com/folder/index.html and example.com/folder/index-filter-stuff.html
Now when I echo $_GET["bla"] from example.com/folder/index.html?bla=value it works, I get the value. But when I echo it from example.com/folder/index-filter-stuff.html?bla=value then it's not working. So I get only values from non rewritten parameters when the URL doesn't contain rewritten parameters, what could be the problem?
