File not found errors

Okay we're getting a lot of file not found errors, but how do we find out where they occurred from?

Best I can see is in the Cookie or AllRaw what the name of the control was (the asp.net clientidmode predictable name)...but I mean that widget could be anywhere.

Thoughts?

Are these 404 errors? You can check the Referrer if it exists to see the page that the user has come from.

I'm not sure if that answers your question though so some more clarification would be good.

Cheers

Hi Steve,

With no referrer its going to be tricky to track down! I saw that the request is using the OPTIONS HTTP method, and the user agent string is "Microsoft-WebDAV-MiniRedir/6.1.7601". After some googling it would seem this is a Windows machine thinking that you have a WebDAV server and attempting to connect to it.

Hope this helps

Martin

Yeah, I know it's near impossible to track down, this was our support guys first day looking at what raygun was showing us :) ...there was confusion as to now we're supposed to solve this one.

So there's no "referrer", however there's a GA tracking cookie with this in it (in the raygun cookies log) _utmli=contentPlaceHolderC173masterListViewctl00ctl00documentsRepeaterSitefinityHyperLink113; I was hoping that could help me track down a page, but I guess it's unrelated and might be some historical thing from another page eh?

Hmm possibly, I wouldn't rely on it though. From the search results I saw I doubt it is a page as such in your app causing the error. The IP address may be helpful in tracking down a particular machine if it is inside your network? Another option is to set it as permanently ignored in Raygun!
