Hi,

I have written an HttpHandler which serves images from the database. The
handler works perfectly, with the exception of the fact that multiple
requests to the handler are serialized.

Since there are sometimes a few such images on a web page, the pages take
quite some time to complete (on the client side).

I have totally deactivated session state for this web app in the
web.config, so i would hope that session serialization is not the problem.

I have even tried writing an HttpHandlerFactory that returns a new
instance of my HttpHandler for each request, but to no avail.

I would be most grateful for any insights ...

Regards
Nick

Nick,

How are you proving that the requests are being serialized? Could
it be that the database access is sufficiently slow that it only
appears that way. Also, it might be possible that connection pooling
is coming into play here.

Perhaps you could post some code. Is your HttpHandler
flagged as reusable?
