Re: unexpected EOF on client side when Apache sends applet class

[steve sawtelle <swsyah@xxxxxxxxx>]

I'll check into timeouts, any idea where they are set? 

I verified it is due to data length, which could be time related. When the data part of the packet exceeds 256 bytes, it fails. If I simplify my applet class to get it down below 256 bytes (192) it loads. The 256 value makes me think it's a length problem, though it seems odd that the protocol doesn't deal with this. I guess I have more to learn...

It did work the other day though and I'm sure the data was over 256 bytes. Very strange.

Are your timeout values set really low? I know I had an issue similar to
