An HTTP client can address a service of a UTM application in different ways. On the one hand, the TAC of the called service can be specified directly in the path of the URL. Alternatively, you can use the openUTM generation to map path specifications in a URL to a TAC. The assignment of an path to a TAC of the UTM application is done with the KDCDEF statement HTTP-DESCRIPTOR.
When an HTTP request is received in a UTM application, the TAC is selected in the following sequence:
openUTM first searches for the path of an HTTP request in the HTTP descriptors assigned to the BCAMAPPL via which the request was received. If the path is not found there, openUTM searches the HTTP descriptors generated with BCAMAPPL=*ALL. If the path is not found there either, openUTM checks whether the path corresponds to a generated TAC. If this also does not apply, openUTM determines whether a path is generated with "/*", first for the BCAMAPPL via which the request was received, then for BCAMAPPL=*ALL.
