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');
apache_setenv
说明
bool apache_setenv ( string variable, string value [, bool walk_to_top] )
apache_setenv() sets the value of the Apache
environment variable specified by
variable.
注意: When setting an Apache environment variable, the corresponding $_SERVER variable is not changed.
参数
variableThe environment variable that's being set.
valueThe new
variablevalue.walk_to_topWhether to set the top-level variable available to all Apache layers.
注释
注意: apache_setenv() can be paired up with apache_getenv() across separate pages or for setting variables to pass to Server Side Includes (.shtml) that have been included in PHP scripts.

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.

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.
