Why not upgrade Apache...?? Both the 1 and 2 series have been updated I think.

Everywhere else, you can indicate an end of data Mozilla has an option to enable http pipelining as a performance option. I regularly used this, maybe I shouldn't?

Considering that there's a warning concerning it's use "with some servers" maybe it doesn't... Luckily it's not on by default.

I've found a better solution! On today's freshports there is something called mod_blowchunks :-) If installed, it will reject chunking and log it. This is an alternative to upgrading Apache.

You mean to say "it believes it is talking to an HTTP 1.1 server", yes? I guess using HTTP 1.0 is a better solution then. Of course, maybe the *best* solution IMVHO would be to upgrade to the Apache version without this bug.
