I will shortly need to run a shopping cart solutions that I have hosted on my main DNN installation.

Each cart will therefore require SSL enabled for the checkout process, 4.5.5 brings SSL support so that is one problem sorted :)

My question is this... IIS6 will only let you have one SSL certificate bound to one web site instance within the IIS MMC.  I understand the principles of SSL and that you can only have one SSL certificate on one IP/Port.

Are there any drawbacks to me creating new Websites within IIS, pointing them at the same document root and using the same app pool, but listening on different IP's/Ports.  This would allow me to deploy different SSL certificates to each site but they would effectively be pointing at the same shared DNN installation.

How would the above configuration affect Memory usage? With using the same app pool would memory be the same? Or would .NET load each SSL instance seperately treating the apps as different application domains?

Has anyone else had a similar requirement?

Thanks in advance.

You will run into problems with caching and the scheduler if you point more than one IIS website at the same DNN install.  They will each get their own app domain even if they are in the same app pool, and you won't save on memory overhead.

With e-commerce and SSL I would recommend that you put each customer in their own website and database.

John,

First time I have heard of the issue regarding multiple IIS websites pointed at one portal. What sort of problems and how severe are they going to be and do you know of any workarounds/fixes that can be used without breaking out each site?

[EDIT] Which versions of DNN does this affect?[/EDIT]

TIA

Antony

What happens is that you get multiple app domains with their own background threads for the scheduler, so any tasks being run by the scheduler have the possibility that the same process will be ran at the same time. This most offten shows up in the search indexer, but it makes all the scheduled tasks run multiple times when they only need to be ran once per DNN install.

You also get multiple app domains for caching, which may not be as bad if the individual IIS websites are all for different portals, but if you start using persitent caching then you will get conflicts with File I/O.

No, there is not a work-around for this. It affects all DNN versions.  DNN is not architected to have multiple app domains using the same DNN Install.  There are provisions for multiple app domains coming from different servers (web farm), but you still should not point them at the same physical DNN Install or you will get the File I/O problems.

Possible alternative for SSL support...

SSLRedirect is an excellent add-on for SSL securing DNN web pages.  SSLRedirect provides the flexibility of using Regular Expressions to define which web pages should be SSL secured.  SSLRedirect also provides an output filtering feature which assists in eliminating the mixed content message sometimes received when flowing from HTTP to HTTPS web pages.  SSLRedirect is the ONE SSL enabling component which works equally as well with native ASP.NET apps as with DNN apps.  SSLRedirect also works with single domain SSL Certificates or wildcard SSL Certificates.
