Question to Proxy in Reading Query String

Question

Hi, our team have a problem, and let me state below:
We use reverse proxy in machine A to redirect to machine B.
Machine A is SJWS 6.1, and it has customized SAF.
The SAF has one mission, which is to retrieve query string from each requests.
The question is:
When the SAF read the query string in body data( with netbuf_getc() ), the application in AP SRV cannot read anything about query string.
In the contract way, if we let AP SRV to process data through query string first, and then we try to get body data( with netbuf_getc() ), NSAPI gets nothing.
Any suggestion?!
thanx.
environment:
================
machine A:
Windows 2003 Server Enterprise (32 bits)
Sun Java System Web Server 6.1 SP5 with Reverse Pxory Plug-in
machine B:
Windows 2003 Server Enterprise (32 bits)
Sun Java System Application Server 8.1 (Enterprise, Platform both have been tried.)

The query string is part of the request URI. It is never part of the request body.
I assume you mean that your SAF reads the request body to extract form data. If your SAF consumes the request body, that request body will not be available to other SAFs.
It sounds like you should consider writing an input filter, not a SAF, that will process the request body. There's information on input filters in the NSAPI Programmer's Guide at http://docs.sun.com/source/817-1835-10/npgcfltr.html.
