CA API Management Gateway
The Layer 7 Gateway has certain protocols in place to ensure that it does not receive messages from an HTTP POST that are too large or transmit messages that may be too large for an endpoint. The Gateway has a hard cap set for the size of an inbound request form parameter of an HTTP POST of 600,000 characters Typically, form parameters operations should not be this large but this procedure will allow an administrator to permit large form parameters in request messages. This behavior was previously documented in development incident SSG-5596.
The following error message may occur when routing a request with a long form parameter:

Append the following line:
