Ugh! Just had the "duh!" moment. It was my CGI script's fault all along.
To get the POST/GET parameters, I was only parsing the QUERY_STRING
environment variable if CONTENT_LENGTH was non-null, whereas I should
have been parsing it if CONTENT_LENGTH was non-null *and* non-zero.
I didn't immediately connect that to the "Content-Length: 0" header
(though it obviously is the same thing), because I knew my CGI script
wasn't parsing the headers, Apache was. But of course Apache just
converts that header to the CONTENT_LENGTH environment variable . . .
Thanks for reading anyway,
Ben

Hi all,
I've got a problem with a "Content-Length: 0" header in GET requests.
I discovered it because some requests from newish mobile phone
browsers weren't working. Anyway, I captured the headers these phones
were sending in the GET request, and narrowed it down to them having a
"Content-Length: 0" header line.
If the request has that "Content-Length: 0" header line (these mobiles
send it), Apache sends the wrong page---it always sends the home page
of the site. If the request doesn't have the Content-Length line (most
other browsers), Apache works fine---i.e., sends the correct page.
So this works (try it with "telnet harvest.com 80"):
GET /he HTTP/1.0
but this doesn't (i.e., returns the site's main page instead of /he):
GET /he HTTP/1.0
Content-Length: 0
(And it's not a HTTP 1.0 vs 1.1 issue---if I add a "Host: harvest.com"
line and change the GET to "GET /he HTTP/1.1" it still has the same
"Content-Length: 0" problem.)
It seems like an Apache or Apache config issue, because I don't think
there's a problem including that "Content-Length: 0" header in the GET
request ... though I could be missing something obvious.
Any pointers or info would be much appreciated. I'm using Apache
2.0.47 under Win32 (WinXP SP2).
Thanks heaps,
Ben.
