mod_proxy and chunked requests

Hi,

I am running Apache 1.3.27 as a reverse proxy using mod_rewrite and 
mod_proxy. We recently encountered problems with PDA client browsers 
using MIDP (J2ME Mobile Information Device Profile) which send their 
requests using a chunked transfer encoding.

mod_proxy as shipped with Apache 1.3.27 does not allow chunked TE and 
therefore refuses to reroute the requests to the origin server.

I looked in src/modules/proxy/mod_proxy.c and saw the following code:

static int proxy_handler(request_rec *r)
{

     .....

     if ((rc = ap_setup_client_block(r, REQUEST_CHUNKED_ERROR)))
         return rc;

     .....
}

What impact would it have to replace REQUEST_CHUNKED_ERROR with 
REQUEST_CHUNKED_DECHUNK? I do not master the mod_proxy source enough to 
forecast any behaviour.

The chunked TE used by MIDP seems unavoidable, the only chance is there:

but it implies efforts on the client application side which servers 
usually do not manage.

Any help appreciated,

Mathias.
