ContentProviderAPI is a service interface which can be provided to the ContentRegistrar interface. It is used to allow KPs to provide Web content through a properly configured Web server.
This interface defines the following object types:
'frob', and a request arrives for http://www.foo.org/cgi-bin/koe/frob/nitz, the url parameter takes the value
'/frob/nitz'. env represents the environment of the CGI script that implements the bridge, with some variables removed to protect the security of the server (and which are non-sensical if the Web server and the KOS are running on different hosts, which is entirely possible). fp is a read/write file interface. It allows the implementation of the GetContent() method to read form data and write the results of the request back to the server. Data passed in and out should match the forms expected from CGI programs.
