mod_proxy bug handling method POST

1. mod_proxy and POST method

Hi,
this is my configuration:

web browser <--> Apache 1.3.24 <-- (mod_proxy) --> oc4j

this is a piece of httpd.conf:

<IfModule mod_proxy.c>
   ProxyRequests On

    <Directory proxy:*>
        Order deny,allow
        Deny from all
        Allow from cheope
    </Directory>

    ProxyPass             /myapp http://myserver:8888/myapp
    ProxyPassReverse /myapp http://myserver:8888/myapp
</IfModule>

all goes well, until I try to open

http://myserver/myapp/logonform.html

where it is a form with an empty POST method (post back to himself).

Now, even if I submit the form (as is), the result is a "broken" response
page... similar to the one I'd like to obtain (the same one, of course),
but incomplete (it misses half page around).
I'm going to be crazy....
TIA
Antonio

P.S.
I've found this patch
http://www.apache.org/dist/httpd/patches/apply_to_1.2.1/msie_4_0b2_fi...
ch
but I'm not sure that is the right one (and besides I would have to
recompile !!!)
