Broke this file out from WamW3.hxx, since WamW3 contains shared stuff
|

and EXEC_DESCRIPTOR is only used in w3svc.dll

/* 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.
