I wrote a scritpt for testing SOAP-Services. It generates and sends
requests to other machines but also receives such requests from other
machines in the net.As there are many 'senders' and muc more URL's they
are sending their requests to, I intended to write a general
SOAP-Request handler, that handles all incoming requests.
Therefore I Configured Apache 2.0.55 using the ErrorDocument directive:
ErrorDocument 404 /soap/dispatcher.php
Now my tool is able to handle SOAP-Requests to any URL that is located
on the Server e.g. (ServerName = spttt.seraph)
http://spttt.seraph/bli/blo/foo (but also)
http://spttt.seraph/sifdino/services/OrderEntryRequestService
Hope you got the it so far.
Now my problem:
The Soap-Rquest handler needs to read the POST-Data that the sender of
the SOAP-Request posted to the script. $HTTP_RAW_POST_DATA should
contain this data but also php://input was mentioned in some
php-mailing-list messages I found in the archives.
My problem is, that my script NEVER gets any POST-Data, if it is called
by the ErrorDocument 404 Rule. If I address the handler directly, the
Post-Data ist there.
When the script is called by the apache errorDocument handler, the
following headers are received:
HTTP/1.1 404 Not Found

Notice the REQUEST_METHOD, which is GET! Obviously the script get's no
POST-DATA in a GET-Request...
- Can anyone tell, if this behaviour is by intention?
- Why are the POST-Data not handed to the ErrorDocument - Script?
- Is there a possibility to solve this (workaround)?
- Im I stupid?
Below further information an my test-scripts:

Apache error-log states:
