Threading in a C# application on asp .net 2.0. How do I thread a parameterized method?

I have 2 applications. 1 is a java application that will connect to a mainframe and retrieve data from it and write it to a location on a given server. The variables used to do this are passed on the QueryString to the java servlet.

I have a .net application that calls the java application in order to queue up data that needs to be retrieved and written. Currently the task is taking a while as it waits for each UniqueIdentifier to be processed before processing the next one. I am exploring the possibility of using threading to accomplish this, but I'm running into a few snags.

So far, everything I've read on threading says the method you are wrapping in the ThreadStart delegate must return void and have 0 parameters. I don't have an issue w/ the void return, but I need to find a way to pass the function the thread runs 2 string values. The thread also writes to an onscreen control when it finishes. It's just a string of text. Will this operation hold up other threads? Lastly, I need to set a limit of 10 maximum concurrent threads as I don't want to bog down the java servlet application.

Here is what I have so far:

               ThreadStart ts = new ThreadStart( this.RetrieveData );
               Thread t = new Thread( ts  ) ;
               RetrieveData( "DataLocation", Uniqueidentifier );

Obviously I'm getting an error like: 'No overload for RetrieveData' matches delegate 'System.Threading.ThreadStart'.

I had read that the cache was thread safe. Is it possible for me to put a list of uniqueIdentifiers in the cache as well as have each thread write it's output to the cache?

Code examples are highly appreciated at this point. Thank you for your time.
