Error description
HTTP OPTIONS request is rejected with 405 Method not allowed on the cics command WEB OPEN if a non-default port and a Proxy server is being used. The problem here is that the response to the OPTIONS request contains a Proxy-Connection header which DFHWBCL doesn't handle. DFHWBCL is expecting a Connection header. Consequently DFHWBCL doesn't detect that the connection is about to be closed by the proxy server.

Problem summary
**************************************************************** * USERS AFFECTED: All CICS users. * **************************************************************** * PROBLEM DESCRIPTION: CICS fails to close the connection to a * * remote server on receipt of a * * "Proxy-Connection: close" header. * **************************************************************** * RECOMMENDATION: * **************************************************************** A CICS application is making an outbound HTTP request via a proxy. A WEB OPEN command is issued which causes an OPTIONS request to be built and sent via the proxy to the remote server. The OPTIONS request gets rejected with an "HTTP/1.1 405 Method Not Allowed" response, and the remote server returns a "Connection: close" header. The proxy modifies the close header to be "Proxy-Connection: close" to indicate that the connection to the proxy server will be closing. CICS doesn't recognize the "Proxy-Connection: close" header , it was expecting to see "Connection: close", and consequently the connection is left open. The application then issues a WEB CONVERSE command. The SEND works but the proxy then closes the connection causing the RECEIVE to fail with CONNECTION_CLOSED.

Problem conclusion
CICS has been changed so that it recognizes the "Proxy-Connection: close" header and will now close and re-open the connection.
