Hello All,
I am using an IHttpAsyncHandler class to intercept HTTP Requests and forward
them to a system which processes the Request and returns the Result.
I use .NET Remoting to connect the IHttpAsyncHandler object to the System
and transfer the Request and Result between the two.
This works fine for quite a while, and then I start to get the following
error.
"This remoting proxy has no channel sink which means either the server has

I am evaluating Mike Woodring's custom thread pool classes
(Developmentor) for use with an ASP.NET project that will be
implementing pages derived from IHttpAsyncHandler. (Recommended by the
famous Fritz Onion article on IHttpAsyncHandler...)
I understand most of the code, however I am at a losss of the purpose of
the ThreadInfo class. It appears that it is used to get the current
HTTP context object for a worker thread?? But, can't...

I am new to ASP.NET, so perhaps this is problem will yield a simple answer.
I am building an ASP.NET application using asynchronous handlers
(IHttpAsyncHandler). In doing so, it was recommended that I use a
custom thread pool to handle work items that are queued from
BeginProcessRequest.
I am using the famous DevelopMentor custom thread pool written by
Mike Woodring.

I am trying to write a program that will continuously sniff eth0 for a specific UDP packet thats being sent to a specific destination IP, alter the data of the packet, and finally transmit it to the destination. My script compiles fine and runs fine until it finds the specific packet and tries to alter the payload of the data. Hopefully someone can give me some insight on why it might be doing this...

Hi,
I tried the packet capture module program.
I did a file transfer using ftp from this host to another server.
But when I ran the program, it was just hanging off and it did not print the src ip, dst ip, src port, dst port.
Should I run this program as a Daemon? If so, how do I do that?
I would appreciate your response.

Hi All,
This is my first time using this interface, so I am sure I am just missing
something stupid. When my Http Handler gets called, the Begin runs and the
delegate runs, but the EndProcessRequest never runs and the page hangs
forever. Any idea why?
Public Class MyAsyncWebHandler
Implements IHttpAsyncHandler
Implements IReadOnlySessionState
