[Klone-users] Create request

[Mickael Auger]

Hi Thomas,

I would prefer to use Klone internal mechanisms to minimize the size of my
executable.
Moreover the KLone mechanism works well ;)

My first need is sample. I want only get a page of another server with
GET/POST parameters. And send the same contents without any treatment (at a
first time, and transform or filter data at a second time).


For example :

My AJAX request get a page (ex: page1.xml) to my KLone server (server A),
this server requests this page to another server (server B). Server B send
page1.xml to server B, and this last server send page1.xml to Javascript.
The server A is is running on a first machine and the server B is ruunnig on
another machine, so my AJAX request cannot get a page on server B cause it's
a remote server.

Schema :

AJAX  --(page1.xml)->  KLone server  --(page1.xml)->  other server  -\

|
AJAX  <-(page1.xml)--  KLone server  <-------------(page1.xml)------------/
