Server & Website CE6 C# Mini210/S

Hello Everyone,

So I've ran into a problem recently, and I'm not sure which route to use. I
have a C# application. I want a simple database that I can remotely change
values to that will, in turn, change values for the C# program. For
example, I can take the information from the app, and write to XML file,
excel file, or db file so that I can load it again when I power cycle it. I
was thinking of using excel, that I can't use html to pull that information
out and edit/update. Then came the thought of using XML. The problem is
that I can't use html to edit XML remotely. For example, the two files XML
and index.html are on the Mini210. I want to load up index.html and make
changes to the XML file via javascript or something. I've read about this
and it looks like I can't make changes remotely. I think I'm down to the
SQL option, but I'm not sure about speed and everything (php, etc). Has
anyone managed to remotely make changes to their C# program's values?

Maybe you can explore the WCF way.

@Jean-Sebastien Breault: Thanks for your reply, but I'm not so sure of
jumping into something I've never used before. 

I've found something that could be useful. An integrated webserver for c#;
too bad it's not for compact framework.

I think I will try to mimic their implementation. Create socket, use
TCPListener, etc

Apparently, in C# there is something called HttpWebRequest if you include
using System.net;
