I've posted the 0.3 release of the myhttp, Web Services Engine for MySQL. DELETE and UPDATE are now supported, and range queries now function properly. The handling of primary keys has been completely rewritten. You can find a copy of it here: http://download.tangent.org/myhttp_engine-0.3.tar.gz The announcement here: http://tangent.org/index.pl?node_id=528 I have also released mod_methods, which implements PUT, GET, HEAD, and DELETE for Apache 2.X. This allows the creation of a simple Webdav like environment to manipulate Apache 2.X webservers.
