Administering web support

When you have configured CICS® to perform a variety of CICS web support tasks, and you have started to respond to requests from web clients, you might have to administer your CICS web support structure and to provide appropriate handling for requests if a resource is unavailable.

About this task

You are helped to administer CICS as an HTTP server by URIMAP definitions that manage your HTTP requests:

Redirect or reject specific HTTP requests dynamically in a running CICS system, if the resources needed by those requests (for example, a CICS program) are not available.
Have virtual hosts created by CICS, which can be managed using CICS commands.

If you do not have URIMAP definitions, you can administer CICS web support at the level of a TCPIPSERVICE resource definition, which manages all requests on a particular port, but managing at the level of the URIMAP resource definition gives greater control.
