In my PHP response I am setting the header "Content-type: application/binary" but that is not stopping PHP from rewriting my response.
How do I prevent PHP from transparently transforming the response to insert the PHPSESSID when the use_trans_sid has been enabled by my webhost? Is it possible to do this without using ini_set or modifying the htaccess file?
Never tried, but according to the documentation, output_reset_rewrite_vars() does the right thing.
This is where you can change INI settings. session.use_trans_sid has a mode of PHP_INI_ALL, that leaves you with
Edit: disregard this, today I learned about output_reset_rewrite_vars
