Stratego Networking

stratego-net is a package you can use to implement CGI based services or access a service at a certain URL using HTTP.

Scenarios :

• write an ATermService
• access an ATermService
• write an XML WebService^?
• dynamicly generate XHTML

Client-side

Use stratego-net on the client-side to:

• download an ATerm^? from an URL
• apply a transformation by invoking an ATermService

Both strategies are implemented in the http-client module. Use http-get-term to download an ATerm from the given URL. With xtc-http-get you can download any file. This strategy should be used in an XTC composition.

  <http-get-term> URL("http://www.foo.com/foo.aterm")

With xtc-http-transform you can invoke an ATermService to do some transformation. This strategy should be used with in an XTC composition. The http-transform operates on terms an can be used outside an XTC composition.

  xtc-io-wrap(
    xtc-http-transform(!URL("http://127.0.0.1/cgi-bin/calculator"))
  )
