47919Re: Executing Java/C# server method from svg

      Sounds like it would be nice to use getURL and postURL in my
      ECMAScript. It says that these will allow you to retrieve data from a
      server using a simple HTTP GET or post data to the server using an
      HTTP POST. But how do I use these to communicate with a C#/Java app
      (that accesses the database) that is running separately on the web
      server machine? Or can I?

      I'm a little confused as to how to do this and I couldn't really find
      any simple examples from the links below. I'm thinking that there
      will be a method call in the C#/Java app that will return the
      results. Does anyone have a simple example or step-by-step
      instructions on how to do this in plain English?

      Or, do I need to use sockets?

      Are either of these methods restrictive to certain browsers?

      Thanks for your help. I am new to alot of this.
