Do > you have an idea what might be causing this lag ? something to do with apache, usually we we see this it's something to do with DNS lookups ... unlikely in your case. I figure it's something to do with apaches' content negotiation, possibly it looks up your content-type for some reason but ends up not recognizing it (and tries alsort of stuff before giving up and just sending the output) http://httpd.apache.org/docs/2.0/content-negotiation.html question is do you really need "application/x-javascript"? won't "text/javascript" do just fine? or does that have the same problem? ... actually does the problem occur with any value for 'Content-Type'? > > Thanks in advance :) > >
