Thanks for the reply Joshua.
Firstly your quite right. The title is the wrong way round. Apologies -
it's been a hard day !!
Secondly, I should explain that I am a web developer and not a server
administrator so I don't have access to very much except to the access logs
at our ISP. I'm simply trying to see whether Apache is the cause of the
problem and whether we can find a workaround to whatever is causing it.
As regards the logs, I have posted some extracts below (with IP No. and date
removed to make them more readable). In the case of the first four, the
response size of 1483 is simply our "Thank You" page following final
submission. In fact no data was received from these submissions. In case
of the last two, it was for a short error message following lack of received
data. In the majority of cases though, we have identical records in the
logs which are showing as POST and where there was successful transmission
of data. Each of the codes below has a 200 response ! In all cases, the
request was sent as POST.

Hi,
We have a web application which had been running unproblematically for
around 6 years until several days ago (approximately 10th May). At this
time we suddenly found that requests sent via POST were intermittently
showing up as GET requests in the Apache access logs. On each such
occasion
(around 10% of requests) the application would fail as a consequence with
none of the POSTed data reaching our scripts. On the remaining 90% of
occasions the POST request were getting transmitted successfully.
So your subject line is backwards.
(a) has their been a recent update of Apache or related software over the
last 10 days which could possibly have caused this problem?
No. And in any case Apache doesn't auto-update, so it would need to be
the result of you specifically changing something in apache.
(b) does anyone have any idea of what sort of process could alter a POST
request from a browser in such a manner as it finishes up as a GET request
without any posted data by the time it reaches a CGI scripts?
Incidentally,
on this point, we are pretty certain that the form is not broken in any
way
and submits a valid POST request.
The most common reason for a POST to change to a GET is that the POST
is redirected. Check your logs for 3xx response codes and figure out
what is generating them.
It isn't clear if you are actually seeing GET or POST in your
access_log. Perhaps you can show us some of the contents of the
access_log.
In the worse case, you should trace exactly what is getting sent back
and forth to apache using something on the wire or something like
mod_dumpio:
