Passing/Storing Sessions on Clustered Server?

[Rob Meade]

Hi all,

At work we have 2 servers in a cluster for our web apps.

One problem we have experienced (along with many others!) - is that if a
user is logged into one of the applications on server a for example and it
goes offline or fails their session is lost also - even though the
application becomes available on server b.

I have heard that it is possible to either exchange the sessions between
clustered servers or store them in a SQL Server database (probably
preferred) so that we could then restore them if such a failure should
occur.

Can anyone shed any light on this for me? Or give me some URL's to check out
and read.

Sorry this isn't a 100% pure IIS question - its obviously partly ASP also.

Thanks in advance for any help you can offer.

Regards

Robb

You will need to "roll your own" sessions by putting the session data into a
database and using a cookie, hidden form field, or URL parameter to identify
the session. There are a number of articles out there on this. Also see
[url]www.aspfaq.com[/url]. There are also a number of 3rd-party "session" objects that
support this behavior as well.

As I understand it, .NET has most of this built-in.
