Tcl API

The following features changes for the Tcl API are included in AOLserver Version 3.0:

Feature	Where Documented
ADP parsers supported: ADP parsers implement a specific syntax for ADPs. Two ADP parsers are registered by default: "adp" and "fancy". Configure ADP parsers in the ns/server/server-name/adp and ns/server/server-name/adp/parsers sections of the configuration file. You can specify a specific ADP parser in the ns_adp_eval Tcl function. You can register new ADP parsers with the Ns_AdpRegisterParser C function.	Administrator's Guide: page 56, page 57 Tcl Developer's Guide: page 10, page 53 C Developer's Guide: page 45
New ADP configuration parameters: Several new parameters have been added, and some other parameters have been removed.	Administrator's Guide: page 56
ADP caching configuration changed: Caching for ADPs is configured with the new Cache parameter in the ADP section.	Administrator's Guide: page 56
Built-in ADP tags no longer supported: The built-in ADP tags, <aol>, <browser>, <msie>, and <netscape>, are no longer supported. You can register your own ADP tags with the ns_adp_registertag and ns_register_adptag functions.	Tcl Developer's Guide: page 58, page 160

New configuration file Tcl functions: The new ns_section and ns_param Tcl functions are used to define the sections and parameters in the configuration file.

Linked interpreters no longer used: Tcl interpreters no longer share the same procedure tables.
