<Runtime System>

[ WWW8 paper | download ]

The Web service runtime system used in <bigwig> contains support for:

  • resident session processes;
  • smart reply pages:
    • no more meaningless reply pages when users click "back",
    • automatic "please wait" pages to inform users of progress,
    • consistent bookmarking of sessions is possible;
  • automatic garbage collection when users do not respond; and
  • accessing the low-level HTTP details through a high-level interface.

Version 2 contains several improvements:

  • Apache module (instead of CGI), for efficiency;
  • improved garbage collection using a special daemon process;
  • complete man page documentation; and
  • full automake/autoconf+RPM support for flexible installation and configuration.

All functionality is available to the service code through a C library. The package is designed to be used both when the services are to be written directly in C, and when C is the target language in a compilation from a high-level Web-service domain specific language such as <bigwig>.
