HTTPS sites very slow and don't work correctly. Please advise...

[CHokKA]

Hi everyone. I am not 100% how to configure the proxy in SBS 2k to allow https sites to work correctly. At the moment we access a few of these sites for things such as banking etc (these sites are not hosted on our server, we have no sites hosted on our server) but they are exceptionally slow. We have to refresh the page numerous times before it'll display correctly, if it'll display at all. Sometimes we can be trying the same page for hours. We have contacted all the companies that these websites belong to, and have spoken to their technical dept's and they all tell us no-one else is having problems with the site. So it leads me to believe that our server here is having problems handling https sites and distributing the information to the local PC through the proxy. Does anyone have any idea how I would go about tweaking or configuring the server so that it'll process https sites correctly, as I'm sure that having to refresh the page constantly on the workstation is not the way it is supposed to work. It even takes forever if I access it from the server itself.

We have SBS 2k on the server, with a 64K ISDN dialup. The server is a Dual PIII 1GHz with 1GB RAM. It also runs Exchange 2000 (we're only a small business so we don't really need a separate file server or mail server on the premises).

To be honest with you I don't really know where to look on the server with reference to https. I have had a look through IIS Admin but it's all site trees for a default website on our server, which we do not use.

Any and all help will be greatly appreciated. Thanks.

The only help I can provide it that I've seen sorts of this where there is a memory cache between the user and the site, either on a proxy server or at the ISP level (as an added service), caching encrypted data can cause alot of problems. For example, cache hists would be at a minimum and the cache data will keep being replaced making responses slow.

Well I've disabled the cache on our server here so it definately won't be that. We've also set the client PC's to force an update of the webpage each visit it makes, so that would bypass the cache anyway (well one would hope it would). We use IE5 and IE6 on the PC's.

I don't think it's an ISP issue either as none of their other clients have this issue. I've just enabled packet filtering and IP routing on the ISA server, restarted the associated services and still no luck. Thanks for the suggestion though

Any ideas as to what else I might try changing?

I've checked MS TechNet and there's nothing else about it other than the IP routing etc. Anyone got any ideas about what I can do to rectify this issue??

Please help out if you can. I'm getting desperate
