If you set a variable, either new or existing, the corresponding $_SERVER variable is not changed, and you will have to change it as well.

If you are using mod_gzip or mod_deflate to compress HTML output, you're not able to send partial file to the browser....

To disable mod_deflate in PHP (if needed), you can tell Apache with this :

apache_setenv('no-gzip', '1');

When you need to set the QUERY_STRING variable into a page included with the "virtual" function do this:

virtual ("some_page.shtml?$QUERY_STRING");

apache_setenv does not work for this case.
