DESCRIPTION

       TSHttpTxnInfoIntGet()  returns arbitrary integer-typed info about a transaction as defined
       in TSHttpTxnInfoKey. The API will be part of a  generic  API  umbrella  that  can  support
       returning  arbitrary  info about a transaction using custom log tags. It works on multiple
       hooks depending on the requested info. For example, cache related info  may  be  available
