Hi
I wish to use HttpClient in a servlet based application. The HttpClient will be used
to communicate with another internal server (always the same server). This
communications will be in HTTP over SSL and I would like to be able to reuse
connections to the server without having to do an expensive SSL handshake all the
time. I would intend to have a long timeout on the HTTP connection (~15 minutes).
Currently in my servlet I have code similar to below,
class MyServlet extends HttpServlet {
static HttpConnectionManager httpConnectionManager = new
MultiThreadedHttpConnectionManager();
static HttpClient httpClient = new HttpClient(httpConnectionManager);
public void init() {
httpConnectionManager.setMaxConnectionsPerHost(150);
}
public void doPost(Req req, Response resp) {
PostMethod post = new PostMethod(url.getPath());
post.setRequestContentLength(PostMethod.CONTENT_LENGTH_CHUNKED);
post.addParameter("TestReq", "Hello");
int result = httpClient.executeMethod(post);
post.releaseConnection();
}
}
This does not appear to work when a few users/threads are accessing the servlet at the
same time. I get the following error message on the executeMethod():
Recoverable exception caught when reading response - couldn't find valid http header.
(or something like that!)
Do you think that this is the correct way to use it if you want to pool connection to
same server (should I use static HttpClient)?
Any help would be greatly appreciated.
Cheers
Sinead
