Feel free to come up with a working version. The path how to handle this is clear. > Don't know what microsoft is doing here (don't have their source ;-). They will do something similar. If you get a HCI trace, then you can see for yourself what they are doing. Regards Marcel ------------------------------------------------------------------------- Using Tomcat but need to do more?
