Hi Wayne, I wasn't talking about compression. I was talking about how the compression will affect caching if it is Not done correctly. By the dev's who write your code and the devs that will write web pages and The back end stuff. Or possibly when a dev utilizes isapi dlls etc. So, nope no mis-communication on my part.

If you want to implement compression for cached content on the ISA server, you need to use a product like ours. -Wayne -----Original Message----- From: josephk [mailto:josephk@xxxxxxxxx] Sent: Friday, July 09, 2004 4:25 PM To: [ISAserver.org Discussion List] Subject: [isalist] RE: XCompress for ISA -- Compression Filter http://www.ISAserver.org Reply below Just my comments Wayne, nothing against you. I just can't see Adding the extra stuff to ISA server. ISA server 2000 and 2004 Have very different object models. I've been working on similar stuff For about 2 years! Lol. I keep finding things that keeps me guessing About how the object model really responds to 3rd party enhancements Thank you, Joseph -----Original Message----- From: Wayne Berry [mailto:wayne@xxxxxxxxxx] Sent: Friday, July 09, 2004 3:52 PM To: [ISAserver.org Discussion List] Subject: [isalist] RE: XCompress for ISA -- Compression Filter http://www.ISAserver.org Joesph, 1) Not every request is intended for an IIS server, i.e. the forward proxy scenario. Let's say you have a ISA server as a proxy that gives your internal users outbound access to the Internet. Some internal users are in a branch office with WAN connectivity over a partial frame relay. You would like them to get faster Internet access, however you don't want to pay for more channels on the frame relay (or faster DSL, or...) so you use compression on the ISA server and those users have faster access. Jk: I have tested different setups that deal with wan and local usage. I would actually have a proxy located at each location. Via my log monitoring I've been able to determine the common authorized sites that are accessed and then setup a job to download that content nightly at different times. Works great and does speed up the cashing of web sites. Not to say that your product will or will not allow faster access. I like using what tools I've bought and not add extra layers on top of my system if It really isn't needed. 2) Maybe your IIS 6.0 server's CPU is taxed from serving ASP.NET pages and you would like to offload compression to your ISA server doing reverser proxy. JK: Yes .NET can tax a CPU but on a twin proc machine, I've not taxed mine at all. If the pages are designed with caching in mind then I've not run into the issue. In setting design patterns I've been able to create some dandy work that keeps pages flowing nicely. I see that by adding compression to the ISA server or offloading as you suggest could cause problems eventually with how .NET actually performs it's caching. 3) Maybe you are caching 50% of the web site's static content on your ISA server, and you would like to compress it before it goes out so that you save bandwidth, in this scenario IIS 6.0 is never called, even though the page might have originated there. JK: Again with .NET or any application if it is not designed well, then you run into issues. What I see from my logs is that if I cache certain items on the web page, on occasion ISA server gives different result codes as in 304's etc. Static content would work well if you did not have to support the multitude of browsers out there. We all know that lately IE has been in the news and some folks are touting going to Netscape! And maybe opera. Opera on the other hand does a nice job when looking at pages that should be served up by a PDA. The other side of .NET is if someone was using the view state incorrectly no cashing in the world will help fix that. 4) Maybe you are using ISA server in front of an iPlanet, WebSphere, IIS 5.0, AS/400, and a Apache server and you want to provide one place to maintain compression software. JK: I'm running Iplanet and WebSphere. These items when talking with compatible IBM products do a great job. These other products have not yet embraced a method of caching such as .NET and IIS 6.0 but, I'm sure that they will add on when they get opportunity. Note: XCompress for ISA is not for IIS, it is for ISA. We sell "XCompress for IIS" for IIS, and that is another story. -Wayne -----Original Message----- From: josephk [mailto:josephk@xxxxxxxxx] Sent: Friday, July 09, 2004 3:39 PM To: [ISAserver.org Discussion List] Subject: [isalist] RE: XCompress for ISA -- Compression Filter http://www.ISAserver.org How does your product differ from the caching and compression that IIS 6.0 offers And why would someone purchase your product when IIS 6.0 works great? Thank you, Joseph -----Original Message----- From: Wayne Berry [mailto:wayne@xxxxxxxxxx] Sent: Friday, July 09, 2004 1:12 PM To: [ISAserver.org Discussion List] Subject: [isalist] XCompress for ISA -- Compression Filter http://www.ISAserver.org ISAList: I will take just a second to blow my own horn and try to get some Beta Testers. We (XCache Technologies) have developed an ISA filter that performs HTTP compression on traffic going through the ISA server in both directions. Basically, HTTP compression is what Google and a bunch of other companies are using to speed their pages and decrease their bandwidth and it doesn't require any client side code -- the browsers know how to decompress since it is part of the HTTP 1.1 standard. I am looking for a few Beta testers that would like to try the product, we have developed in conjuction with Microsoft and they are testing it already for us. Just write me off the list.
