Can't show the 413 Request entity too large error page

[Victor Tsang <htsang@xxxxxxxxx>]

I have tested this with the lastest IE and FireFox, it appers that if
I try to upload a file with size larger than what I have specified
with the=20
request_body_max_size option, I get an popup that says 'document contains no=20
data' instead of the 413 error page I expect.

any idea if this is a config problem in my squid or a browser bug?

Many thanks.
