Is there a way to override the headers that session_start() sends to the browser from within a PHP script? On php 4.0.4pl1 (will be upgrading to 4.1.1 later) on SOME browsers (notably, IE 6.0 on XP -- my setup), a script I have that outputs a PDF document will misbehave in IE when the "No-store" portion of a cache-control header is present... which PHP sends as part of the sessions.
When this is present, IE6 will either come up with a blank page, or it'll present your typical "You are downloading the file: blah blah blah... would you like to open the file or save it to your computer?" dialog box. However, the 'open' option of the dialog box will be grayed out, and clicking Save yields an error message reading "Internet Explorer can notnot download <location> from <host>. Internet explorer was not able to open this Internet Site. The requested site is either unavailable or cannot be found. Please try again later." Like I said, it seems to be the "No-store" part of a cache-control header that causes the problem. Change the caching options for sessions from nocache to private fixes this, but happens to break other things on the site. Sending my own cache-control headers with header() either merges them with the ones the session_start sends, or does absolutely nothing (verified by doing a GET /url HTTP/1.0 via telnet to port 80), regardless of whether the header occurs before or after the session_start. -- Daniel Grace P.S.
