Acronym: Long Running Web Process

iMatix, the maker of the open source Xitami webserver is also the maker of LRWP, which is Xitami's method of handling persistent CGI connections.

Those familiar with ASP, or PHP, or Perl used as cgi scripts, may be familiar with the concept of a persistent CGI connection, which gradually feeds the user information, usually based either on information that only becomes available while the user is connected, which is usually a result of user interaction, or in my experience, active monitoring.
