Finding modem speed

Hello,

I'm trying to build an intellegent website that will automatically detect the user's connexion speed and resolution and provide them with the appropriate website. Using javascript to find a computer's screen resolution is pretty simple, but I was wondering whether there was a way of using it to detect the speed of the modem/connexion the user was running.

If this is not possible through javascript, is there another tiny piece of code that will do this? Perhaps there is a way of telling how long it took to download a particular page & then use that to decide which site to send the user to.

Thanks,

but I'm interested in trying to do this for myself. Call me stingy, but I'd rather not pay someone $1 a month for sometihg which I imagine to be relatively simple. The fact that I am working on website for a church also means that I want to keep the costs right down. I have waived my fee & I wish to do everything else as cheaply as possible.

Thanks

Sam

I also found this, it allows you to check through javascript.

Thanks

That seems extremely helpful. I take it that I just post the script on the homepage & redirect people fron there. If not, please let me know

Thank you for your help
