Just thought I'd share a problem I've found with IE 6 and sites (like mine) that insist on cookie support.
If you use cookies on your site and you send a customer an email containing a link to your site: If the customer's email address is based at a web based mail service like hotmail, IE 6's default behaviour is to disable cookies when the customer clicks on the link and your site is opened in frames. This is because IE 6 considers your site to be a third party (the frames cause this) and unless you have a compact P3P policy set up, which it approves of, it disables cookies. A compact P3P policy is just an HTTP header containing an abbreviated version of a full P3P policy, which is an XML document. Here's how you set up a compact P3P policy under mod_perl: #This policy will make IE6 accept your cookies as a third party, but you should generate # your own policy using one of the apps at the W3C site. my $p3p_compact_policy = "CP=\"ALL DSP COR CURa ADMa DEVa TAIa PSAa PSDa IVAa IVDa CONa TELa OUR STP UNI NAV STA PRE\""; $r->err_header_out(P3P => $p3p_compact_policy); $r->header_out(P3P => $p3p_compact_policy); Check out http://www.w3.org/P3P/ for the full info on P3P. Check out http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnpriv/html/ie6privacyfeature.asp for M$ info on IE6 and cookies/privacy Appologies for the OT post, but I'm just hoping I'll save someone else the same trouble I just went through. ~mark
