Re: Compressed HTTPS



Thanks for the replies from all of you.

Unfortunately if this is introduced it will be mandatory , not negotiated. 
The server in question does not receive connections from browser clients, 
only https in program form, i.e. as with httpapi on iSeries.

I will wait for the tech spec before getting deeper into this.

Thanks again

Ian Patterson
