Hey mate
ISA is not the way forward here. My recommendation is to buy a WAN optimiser such as a riverbed steelhead box to solve this issue. http://www.riverbed.com/products/appliances/ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Christopher Scalley Sent: Wednesday, 22 October 2008 8:07 AM To: [email protected] Subject: [OzMOSS] Using ISA Server with WSS 3.0 - not caching I hope one of you will be able to help with a problem we are having using ISA Server with WSS 3.0. Background - the business issue . We host WSS 3.0 sites in our Sydney office that are accessed over WAN links from other offices (Canberra, Brisbane, Melbourne). These sites are actually project workspaces in a Project Server 2007 system. . Each site contains a document library and in some cases the documents are quite large (above 5MB). The documents are typically Microsoft office documents (Word, powerpoint, etc.). . Users in the interstate offices are experiencing slow times to open or edit documents from the document library (even during times when WAN usage is low). Our proposed solution . We plan to place an ISA server in each interstate office, which we are hoping will be able to cache the documents from the document library. . We are testing use of an ISA Server (2006) in our Canberra office. The problem we're having . We are finding that when a user opens a document (by left clicking in the document library) the requests instruct the ISA server not to use a cached document, which is causing the ISA server to always redownload the document. When we look in the ISA log, the cache info says: "0x44000005 Request should not be served from the cache. Request includes one of these headers: CACHE-CONTROL:NO-CACHE or PRAGMA:NO-CACHE. Response includes the WWW-AUTHENTICATE header. Response should not be cached." . If we instead download the document in the document library by right clicking the document and selecting "Save Target as", then the ISA server will use its cached document. However users obviously don't normally access documents in this way. Could anyone provide any ideas on what might be happening? Or if you have an alternative solution to increase performance over a WAN, I'd be very interested in that also! Thanks for your time.
