WebResource.axd

[Mondeo]

Im getting intermittant errors from my global exception hander mentioning this file, its simply Path /WebResource.axd was not found.

What is this file, what does it do etc? And why would I be getting this error?

Thanks

WebResource.axd is a special URL provided by ASP.Net 2.0 which is used to serve resources which are embedded in an assembly (images, scripts, css, etc). An example would be the form validation scripts which are part of the ASP.Net server controls. Note that the file WebResource.axd does not physically exist!

As for why youre getting 404s on this URL, that is certainly unusual behaviour. I would suggest trying Google etc. For example, this page may apply to you.

Good luck

I think I know why the 404s were being generated. At the time we were running a web crawler type application to check for broken links, its a brand new site and we were just giving it the final checks.

I presume somehow this app tried accessing the file somehow in a way that wasnt expected and it triggered these errors.
