I'm deployed a mixed 5.2 and 5.3 environment (ie: some app-servers are running 5.2 apps and some app-servers are running 5.3 apps). Will the adaptor shipping with 5.2 work 100% OK dispatching requests to 5.3 apps or should I upgrade that to a 5.3 adaptor and assume it is backwards compatible?

I had a very weird issue last night with stuff I just don't understand right now: I have a box with 10.3.x installed, acting as the WebServer, the adaptor installed is the one, that came with WebObjects 5.2.3. This server connects to applications on a machine with 10.4 where the applications and the database are installed (latest WO that came with 10.4 Server).

Now, when somebody uploads a jpeg from a Windows machine (Firefox and IE 6 tested) to the app and the app sends the image through the Quicktime for Java to resize it, the application deadlocks. This doesn't happen when you upload the same jpeg with a Mac (Firefox, Safari tested). But it works on Windows too, when you connect through a WebServer installed on the 10.4 machine.

So, something in the chain of WebServer <---> Adaptor <----> Application breaks that stuff so badly, that the application dies when you upload a jpeg file with Windows.

This should be considered just as a warning to be careful, what you might assume should work ...
