/* EXEC_DESCRIPTOR block
This block is used for all ISAPI and CGI execution. The point is to
remove the hard dependancy on HTTP_REQUEST members when executing a
gateway. This allows for ISAPI apps to also execute gateways.
Instead of referring to HTTP_REQUEST members, when doing an execute,
refer indirectly through the member pointer of this block. (i.e.
_strURLParams.Copy( foo ) becomes pExec->_pstrURLParams->Copy( foo ) ).
For the case of a regular gateway execution by the server, these pointers
refer to the HTTP_REQUEST object (as before). But when an ISAPI app needs
to execute a gateway, the pointers point to local storage so as to not
corrupt the HTTP_REQUEST object.
