Just to clarify - after this case integrates, the existing (non-ZTS) libphp5.so will continue to be shipped unchanged? > 2.3 PECL "memsession" extension > > ? ?This extension can store PHP sessions in-memory.

So this extension is only available for the ZTS module?

Why is memsession split out into a separate package? As a general comment, this case introduces functionality for 3 things: ZTS, nsapi, and sun-webserver-7. It's not clear to me from the case how these three aspects interact, and whether some of them may (or may not be) useful in other contexts. -- -Peter Tribble http://www.petertribble.co.uk/ - http://ptribble.blogspot.com/
