Content-Type header check is not case insensitive, again #19
Description
This is the same Issue as #10.
It has been fixed in branch 1.x-dev, but the fix has not been applied to branch 2.0-dev which appears to be the branch that is included in current joomla releases.
Quick summary:
Treatment of Headers does not respect case-insensitivity of HTTP Headers as of RFC 2616.
E.g. when checking the Content-Type header, this could just as well be named CONTENT-TYPE or content-type.
Please apply the fix also to current development branch and release a version that includes the fix.
It stops us from being able to upgrade Joomla without manually tweaking this problem.
