Privatization of Some Data Structures

The data structures in nsapi_pvt.h are now considered to be private data structures, and you should not write code that accesses them directly. Instead, use accessor functions. We expect that very few people have written plugins that access these data structures directly, so this change should have very little impact on customer-defined plugins. Look in nsapi_pvt.h to see which data structures have been removed from the public domain, and to see the accessor functions you can use to access them from now on.

Plugins written for Enterprise Server 3.x that access contents of data structures defined in nsapi_pvt.h will not be source compatible with Sun Java System Web Proxy Server 4, that is, it will be necessary to #include "nsapi_pvt.h" to build such plugins from source. There is also a small chance that these programs will not be binary compatible with Sun Java System Web Proxy Server 4, because some of the data structures in nsapi_pvt.h have changed size. In particular, the directive structure is larger, which means that a plugin that indexes through the directives in a dtable will not work without being rebuilt (with nsapi_pvt.h included).

We hope that the majority of plugins do not reference the internals of data structures in nsapi_pvt.h, and therefore that most existing NSAPI plugins will be both binary and source compatible with Sun Java System Web Proxy Server 4.

Plugins written for iPlanet Web Proxy Server 3.6 will not be binary compatible with Proxy Server 4. These plugins will have to be recompiled and relinked using Web Proxy Server 4’s NSAPI header files and libraries.
