From f6801d669ee11f0d5e67b2e86aec270d2a225224 Mon Sep 17 00:00:00 2001 From: Alp Toker Date: Tue, 11 Jul 2006 11:19:34 +0100 Subject: gitweb: Send XHTML as 'application/xhtml+xml' where possible "The 'text/html' media type [RFC2854] is primarily for HTML, not for XHTML. In general, this media type is NOT suitable for XHTML." This patch makes gitweb use content negotiation to conservatively send pages as Content-Type 'application/xhtml+xml' when the user agent explicitly claims to support it. It falls back to 'text/html' even if the user agent appears to implicitly support 'application/xhtml+xml' due to a '*/*' glob, working around an insidious bug in Internet Explorer where sending the correct media type prevents the page from being displayed.
