In defence of Java, which I think is a great language/environment, my requests aren't over any particular sluggishness or dropped connections.
It is just that I have an application that when started creates a cache derived from the database and uses this to speed up selection and searching on data that is not easily index-able. It is nice to get this out of the way before the first request :-) I think your suggestion re a script is sound - I have used something similar in the past. Hacking the wsgiserver.py module is probably beyond me at this time. Probably the answer is convert to python, run on first request and consider options if it's a problem. Thanks.
