PK27675: OPEN_SESSION PROXY_ERROR TRAILING SPACES ON IP ADDRESS WHEN USING EXEC CICS WEB OPEN AND SPECIFYING URIMAP. SSL OVER PROXY

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When using EXE CICS WEB client API commands with URIMAP (e.g.
  EXEC CICS WEB OPEN URIMAP) and trying to establish an SSL
  connection through a proxy server, it can fail with an I/O
  error.
  Looking at the traces from the proxy server, the hostname will
  have blanks appended to the end.  For example:
  .
   Client sez.. CONNECT www.myip.com     :8002 HTTP/1.0
  .
  The CICS region will see an HTTP 403 error, forbidden.  What
  should appear instead is
  .
   Client sez.. CONNECT www.myip.com:8002 HTTP/1.0
  .
  Notice that there are no more intervening spaces in the IP/PORT
  string.  The failure can be seen in a CICS trace on a WB 0713
  trace entry, as in the following:
  .
  WB 0713 WBCL  EVENT - HOST FOR XWBOPEN EXIT
    1-0000  19947FBE
    2-0000  0011
    3-0000  A6A6A64B 94A88997 4B839694 40404040  40
  .
  followed by:
  .
  WB 0701 WBCL  EXIT - FUNCTION(OPEN_SESSION) RESPONSE(EXCEPTION)
          REASON(PROXY_ERROR)

  condition can result if the HOST attribute has a port number
  specified and an SSL proxy is used.

Problem conclusion

• DFHWBCL has been changed to process the URIMAP attribute HOST
  in the same way as the equivalent parameter on the WEB OPEN
  command.
