Multpart Post Problem

[Da...@thomson.com]

Greetings,
 
I am creating a Post method using a MultipartRequestEntity that is used
for a login request to an https site (The login form on the page uses
multipart/form-data even though there is only form data involved). I'm
using a Part array with StringParts for the login and password. The
problem is that the response code is 200 but the login fails (login
and/or password is incorrect), even though the information is correct.
If I remove one of the StringPart objects in the Part array, the
response page indicates that both login and pw are required, so it looks
like the server is able to parse the request, but somehow the form data
is not handled correctly. Could this be some sort of Content-Length or
boundary problem?
 
I've been struggling with this for a few days now and can't find
anything in the archives. Any help would be appreciated.
 
Thanks,
Dave

Thanks, Roland. We finally solved our issue by excluding the content
type and transfer encoding headers from the request. I'm not exactly
sure why one works and the other doesn't, but here is the solution: 

//Using this fails
  	Part[] parts = {
     		new StringPart("login", login),
     		new StringPart("password", password)
     	};
//This works
     	StringPart part1 = new StringPart("login", login);
     	part1.setContentType(null);
     	part1.setTransferEncoding(null);
 
     	StringPart part2 = new StringPart("password", password);
     	part2.setContentType(null);
     	part2.setTransferEncoding(null);

	Part[] parts = { part1, part2 };
 //create the request entity
 	MultipartRequestEntity mre = new MultipartRequestEntity(parts,
postMethod.getParams());
 	postMethod.setRequestEntity(mre);
 
Thanks,
Dave
