Subject RE: Filter Chains slow first time it is called

Thanks for your prompt reply, and sorry for my delayed reply (I was out
of the office yesterday).

A .war file containing an example is attached to this mail.

IE 5.5 and Netscape 6 are both 1.1, I believe. The protocol used by a
WAP 'phone depends on the gateway, not the handset, and I'm afraid that
I don't know the answer for the particular gateway that I'm using.

Yes, I create a wrapper (although in the example, the wrapper doesn't
actually *do* anything ;-)

I agree. As you can see from my code, I've added as many "flush" and
"close" statements as I can, with no effect unfortunately!

Thanks again,
