Hi,

Is it possible to reference a custom SoapExtension instance from within a
WebMethod?

I have a SoapExtension used by several web-services for generic logging.
The SoapExtension logs the ServiceId, Soap Request, Start Time, End Time
etc. to the database. I need to get the Id of the row the SoapExtension
inserts into
the database from within the Web Method. (The web method sends a
text-formatted request based on the SoapRequest to an external system and
that needs to be logged in the same database row)

Has anyone had a similar problem?... and if so, how did you approach it?

-Trevor

Hi,

Are you hosting the web service in IIS? If so, the SoapExtension can can
store the Id into HttpContext.Current.Cache with a known key. The web method
can then get the Id from the cache using the same key.

Sami

Hello Sami,

Thanks for the idea but unfortunately that will cause problems with concurrent
requests because one Id may overwrite another.

"The Cache has some similarities to the Application object and is a container
of global data (as opposed to session-specific data)"

I might end up using Session though which is along the same lines.

You are right, using the Cache you would have to handle concurrent access.
HttpContext.Current.Items, on the other hand, is per-request and should be
safe from concurrency issues.
