How to write a HttpModule to replace built-in Session?

[Danny W]

Hi There!

Is it possible to use HttpModule to replace the built-in ASP.NET Session
object? I want to write a HttpModule that will handle storing and retrieving
of session values from an external database.

For example, when a page set values to Session object such as
Session("somevar")=1 then I want my HttpModule to get notified and store the
value into the external database. The same for "getting" the variable, I
want my own HttpModule to retrieve the values from the database.

Any pointers to code samples or tutorials are much appreciated.

What is wrong (read: why do you want something different) with storing
the session-state in sqlserver, which is already supported?

By the way: It's not an "HttpModule", as those handle incoming requests.

Hi Hans,

Well, I do not have SQL Server and I do not have enough $$$ to buy one.
Besides, creating your own gives you more control and flexibility you need.

Any help on my question?

Cheers,

I never try to do this but, I think you must :

1 /
remove the default session state module in the configuration file
add your own session state module

<httpModules>
<add type="Foo.MySessionState" name="MySession"/>
<remove name="Session"/>
</httpModules>

2 / Create your own SessionState module by implementing the IHttpModule
interface. I suggest you to use Reflector to see default session state (class
SessionStateModule) management.

you can use the free version of sqlserver (msde). the session manager just
calls two procs, so you can easily change them.
