I have to concur that generalized transaction support should not be pursued by this working group. General transaction support is a hard problem ("Transaction Processing: Concepts and Techniques" (a good guide to the issues) is over 1000 pages, not just a journal article). It will likely take a look at the whole issue before transaction processing can be added to HTTP. (It may even take HTTP 2.0 to do so.) ========================================================== Mark Leighton Fisher Thomson Consumer Electronics fisherm@indy.tce.com Indianapolis, IN "Browser Torture Specialist, First Class"
