404s - HTTP_X_BLUECOAT_VIA

[LenHewitt]

Since updating a site to XHTML I'm seeing regular 404's in which the PHP $_SERVER array is listing:

HTTP_X_BLUECOAT_VIA :

Anyone have any ideas why this may be?

Welcome to WebmasterWorld LenHewitt,

I believe it is a proxy header, I see it in anon proxy banning scripts.

Thanks, Jatar, but the question really is why should it be generating 404's when the request appears to be perfectly valid?

[jatar_k]

that header shouldn't cause 404s

does the page they were originally requesting exist?
is there some kind of anti proxy coding on your site?
