I turned on info and it says the reason is client didn't send
"Content-Length" header. Now, why would Firefox (3) not do that? Is this
I noticed in Firebug that the header sent ALSO has "Transfer-Encoding:
I had the same problem with Lightpd and using a Flash uploader but they
refuse to fix it to ignore chunked, so I could not use it with Flash.
One reason I switched to using nginx is that unlike Lighttpd it works
with the flash uploader.
So should I just ignore this as it still works as expected? But I
cannot see content in Firebug, or maybe I need to force a header in JS
code (maybe the mootools JS library mistakenly doesn't set the Content
Length hmm, I should explore that too.) Just a minefield. How is it that
the server returns this error page but also I am getting the JSON data
back as well?
