so you need to speak a little bit of client side HTTP from inside a  
kl1 page.

Basically you have two options:
(1) use off-the-shelf HTTP library code (e.g. libcurl);
(2) create the client code you need by yourself by reusing klone  
internal mechanisms (libio/libpage).

The choice depends on (at least) two factors: the complexity of your  
protocol (i.e. basic GET/POST over HTTP/S vs ...), and the need to  
minimize the size of your executables.

Implementing (2) should be roughly 200/300 lines of C code - which  
means a non-significant increment in overall size.

On the other side, doing (1) with libcurl can be 1/5 of complexity but  
a 2M increment if you link it statically ...

The choice is up to you :) anyway, if you decide to go for (1) and  
need some hint/help, just ask !

ciao, t.
