How did you make sure of this ?If not already done, use some browser add-on (Fiddler2 for IE ?) or Wireshark, and really make sure that this is what happens.
Is there a way to prevent apache from modifying my 304 responses?
Which version of Apache are you using ? Now about the rest : quote Because this web-application is integrated into another web application using an iFrame, and because most of the users use IE 7.0, I have to set a P3P CP="CAO PSA OUR" header in all http responses in order to maintain my cookie on the browser. unquote I am really not competent to judge if the above is correct or not. I have some doubts though, thinking about how cookies ought to work.I never heard before of an obligation to set some P3P header to force a browser to keep a cookie.
But anyway, looking at the HTTP RFC 2626, section "10.3.5 304 Not Modified", it seems to say that the set of allowable HTTP headers for a 304 response is quite limited. Might this not be a case where Apache follows the spec, and removes HTTP headers that are not allowed, while IE doesn't follow the specs, and expects such as header ?
