Minor exception for bad browser HTTP headers

Some browsers (probably bots or spiders or something) send bad header information. This causes calls to HttpContext.Current.Request.Browser.MajorVersion (and MinorVersion) to throw an HttpUnhandledException, which is not handled by Kentico.

You should wrap a try/catch block around the two calls to the Version properties in App_Code/Global.asax.cs lines 411 and 441. (from Kentico version 3.1a).

Member	Mufasa - 1/22/2009 3:24:07 PM RE:Minor exception for bad browser HTTP headers Well, because of the clever code you wrote for the Event detail on the Event Log in IE, I can't cut & paste the log message directly. But basically it's just what I said above. It throws an HttpUnhandledException and I tracked it down to the lines I mentioned originally.

Kentico Support	kentico_jurajo - 1/26/2009 2:15:33 AM RE:Minor exception for bad browser HTTP headers Hi, Yeah, you are right, I will try to ask our CTO to make it "copyable". Anyway, you can easily make a screen shot and send it to use to suppot@kentico.com We need to see the stack trace (e.g. from debug) to see where exactly is the exception thrown. Thank you in advance.
