hello everybody.

i want to create an appliction that will work in the background , when the brwoser wants to reach a specific url and download a html page from the server it will sent a request to the appliction , then the appliction will connect to the server and download the html page and pass the page to the browser (the application won't parse the html code) .
in simplier words the appliction is like the outside world for the browser something like a local proxy server .
does anyone have an idea of how to do it - you can send me links to the msdn or links to articels or totrials .
i have another small question , there is a certain chat that i'm using , usually
the window of the chat is minimized in the task bar , when someone apply to me in the chat the window start to blink in the task bar , the problem is that i'm not always looking at the screen and i would like it to make a beep sound besides only blinking.
the chat application is a part of a the browser window .
it's improtant to emphasize that we're talking on something that is connected to the window itself and not to the chat application , the window pickup the change in the chat application and then starts to blink .
does anyone have a solution , somehting like a special browser or a change in the registry settings or a simple VB application .

thans , roni.
