Hi,

I a writting a analysis of a current PERL system which has a server pl
file that opens a socket to listen to incoming message. On the client,
there is another pl file which create a socket to send messages to the
server. The webforms are basically HTML which calls pl files to
process the incoming message, which are saved to text files.

I recommended the following upgrades:

OPTION #1

1. Replace the server socket listner pl file with WCF web service

2. Replace the client pl with a regular C# execute which accept
argument and send the SOAP message to the WCF mesage

3. Replace the HTML webforms and all the pl helper subroutine files
with ASP.NET

4. Replace the flat text files with SQL SERVER Compact (no database
server - not on budget)

OPTION #2 ?

Is there is an cheaper alternative instead WCF web services. Can a
simple C# socket listerner or something else to developed to

replace the PERL socket listener. Basically a .NET replacement. If so,
how can it be hosted on the IIS. WCF can be deployed in an application
pool to handle many requests. How will a simple C# listener do this?

Can the PERL client be replace with a C# executable that does not open
a socket but send soap message to the web server and the c# listener
to process the requests.

The current HTML files are embeded with PERL references to process the
requests. If the clients want to keep the HTML as is, what can replace
the PERL references in the HTML files to process the request.
What .NET technologies?

Are there better upgrade options. What are the other technologies to
upgrade this very old PERL system? Other technologies is good to hear.

Thanks,

If the messages are structured then WCF is definitely a good choice.

If the messages are unstructured - one byte array or one string - then
a socket server in C# would also be a viable solution.
If so,

You can host WCF in ASP.NET/IIS or in itself.

A socket server should not be hosted in ASP.NET/IIS - it should
self host.

Why should that be a problem? A windows service should work fine.
Can the PERL client be replace with a C# executable that does not open

A C# client can use both a WCF service and a socket server.
The current HTML files are embeded with PERL references to process the
requests. If the clients want to keep the HTML as is, what can replace
the PERL references in the HTML files to process the request.

Don't mix HTML with code.

Most technologies could do this job.

Java
Ruby
Python
