Eugen Covaci commented on HTTPCLIENT-2074:
------------------------------------------
[~olegk] I want the Socket Server to act as a proxy. That is to receive the
request made with "httpClient.execute(target, request)", parse the request, get
the URI (which is "www.iana.org:443"), perform the CONNECT then give back the
response. Using HttpClinet v4.5.12 I get "request.getRequestUri() = /" instead
of "request.getRequestUri() = www.iana.org:443" The same code using HttpClinet
v4.5.12 gives me "request.getRequestLine().getURI = www.iana.org:443"
> HttpClient incorrectly parses the CONNECT request URI

> Key: HTTPCLIENT-2074
> URL: https://issues.apache.org/jira/browse/HTTPCLIENT-2074
> Project: HttpComponents HttpClient
> Issue Type: Bug
> Components: HttpClient (classic)
> Affects Versions: 5.0
> Reporter: Eugen Covaci
> Priority: Major
>
> I do have a server socket listening on a local port. Using Postman, I'm
> making a CONNECT request to the server socket for an random address, let's
> say www.iana.org:443. Then I'm trying to parse the request using:
> {code:java}
> SessionInputBufferImpl inputBuffer = new SessionInputBufferImpl(bufferSize);
> ClassicHttpRequest request = new
> DefaultHttpRequestParser().parse(inputBuffer,
> localSocketChannel.getInputStream());
> URI requestUri = request.getUri();
> {code}
> The requestUri I get is "/" instead of the initial "www.iana.org:443".
> Also, calling request.toString() I get "CONNECT www.iana.org://null/" which
> is definitely wrong.
