Redirects not working on Expression Web 2

[thomasvsundert]

The global variable $is_IIS checks if the server is an IIS server or not. This has consequences for the way redirects etc. are implemented. The Expression Web software from Microsoft also uses an IIS-based development server, but here the value of
<nowiki>$_SERVERSERVER_SOFTWARE?</nowiki> is 'ExpressionDevServer'. Since all of the 'hacks' specific to IIS also apply to the Expression Web server, the check for IIS should also check for it.

$is_IIS = (strpos($_SERVER['SERVER_SOFTWARE'], 'Microsoft-IIS') !== false || 
strpos($_SERVER['SERVER_SOFTWARE'], 'ExpressionDevServer') !== false) ? true : false;

Attached patch based off reporters information.

Untested against Expression server

Removes some unneeded brackets and ditches the ? true : false; since thats exactly what the expression resolves to anyway.

Traction? Testing?

I tested the logic, and it seems fine.

Needs testing on a real ExpressionWeb server.

punting to future, from lack of reporter-feedback

A new patch which was tested with Expression Web 2 has been uploaded.
