* @ library / test / lib
* @ run main / othervm NTLMHeadTest SERVER
* @ run main / othervm NTLMHeadTest PROXY
* @ run main / othervm NTLMHeadTest TUNNEL
* @ summary test for the incorrect logic in reading ( and discarding ) HTTP
* response body when processing NTLMSSP_CHALLENGE response
* ( to CONNECT request ) from proxy server . When this response is received
* by client , reset ( ) is called on the connection to read and discard the
* response body . This code path was broken when initial client request
* uses HEAD method and HTTPS resource , in this case CONNECT is sent to
* proxy server ( to establish TLS tunnel ) and response body is not read
* from a socket ( because initial method on client connection is HEAD ) .
* This does not cause problems with the majority of proxy servers because
* InputStream opened over the response socket is buffered with 8 kb buffer
* size . Problem is only reproducible if the response size ( headers +
* body ) is larger than 8 kb . The code path with HTTPS tunneling is checked
* with TUNNEL argument . Additional checks for HEAD handling are included
* for direct server ( SERVER ) and HTTP proxying ( PROXY ) code paths , in
* these ( non - tunnel ) cases client must NOT attempt to read response data
* ( to not block on socket read ) because HEAD is sent to server and
* NTLMSSP_CHALLENGE response includes Content - Length , but does not
* include the body .
