intercept the HTTP calls from SEV plug-in client

Hello,

I need to intercept the HTTP calls from SEV plug-in client

== Log from SEV client (copy/paste from a post found in this forum)

HTTPArchiving::ArchiveItems

Sending HTTP request: http://EVSERVER.DOMAIN.local/EnterpriseVault/clientaction.asp?act=0&fdrenc=_&dn=/o%3dEXCH2003/ou%3dFirst%20Administrative%20Group/cn%3dRecipients/cn%3datest&svr=EXCH&sid=1B53AF7FDC9885A4D8909CB9C7A64304A1d10000evserver&tsp=2014-02-19T13:36:13&pdl=AAAAAAAAAPOKDPLPHHPDNFEJJDLKEPMEHEEMLNEKABAAFBJHCMGALJNOLNELLLGFPAB

My question :

=> I need to access the Exchange server with the information supplied by the URL in order to READ/DECRYPT (if crypted) before passing the original HTTP request to the SEV Server.

I know that there is a MAPI properties with a DATE, referenced by the '&tsp' argument, I wonder if '&pdl' is the folder name where the pending (to be archived) document are located.  In other word, what is the SEARCH I need to do onto Exchange to retreived these documents.

Many thanks in advance

Laurent.
