Just wanted to reply and let you guys know that enabling chunked
encoding solved my connection issues with CICS.  Thanks for all the
help, I would have never found this solution without your assistance.

Thanks-
Joe

That log statement indicates you haven't enabled chunked encoding in the
connector config (it's off by default).
Add enable_chunked_encoding=true to your isapi_redirect.properties (or
as a registry setting if you're using that) and restart IIS.

I have tried the isapi_redirect.dll Tim provided, and it appeared to
almost work.  CICS made the request and received my response but for
some reason did not interpret it correctly.  Is there something in the
redirector's log that I can look at to verify it is using chunked
encoding?

I see the following line, but never see one where chunked encoding is
true.

[Tue Jan 08 08:05:07.220 2008] [13680:12960] [debug]
init_jk::jk_isapi_plugin.c (2146): Using chunked encoding? false. 

Thanks-
Joe

In Joes case CICS seems to get used as an HTTP client, not an HTTP
server.

Nevertheless the server page you found includes a link to

http://publib.boulder.ibm.com/infocenter/cicsts/v3r1/topic/com.ibm.cics.
ts31.doc/dfhtl/topics/dfhtl_cwschunking.htm

that contains the following information:

=======
When CICS as an HTTP client receives a chunked message as a response to
an application program's request, the chunks are also assembled before
being passed to the application program as an entity body, and any
trailing headers can be read using the HTTP header commands. You can
specify how long the application will wait to receive the response,
using the RTIMOUT attribute of the transaction profile definition for
the transaction ID that relates to the application program.
=======

So it seems, that CICS 3.1 does support chunked encoding when reading an
HTTP response.

So using either apache httpd or the chunked-encoding enabled variant of
the isapi redirector could indeed be the solution.

Regards,

Rainer
