Is there a way to determine if a user is using broadband or dial-up

We have a requirement from the client to provide a “lite” version for dial-up access and all calls and whistles for a broadband user.

The solution will use Flex / Flash / Java EJB and some jsp.

Is there a way for a web server to distinguish between two?

You do not care about the type of user connection, you care about download speed.

You have a tiny flash application that loads the rest of the flash memory and how long it takes. Or an HTML page in which Ajax load time.

  • ask user
  • perform a speed check and ask the user if the result is found correctly.
  • Run a speed test and hope that the result is found correctly.

I think a speed test should be sufficient.

If you have only a small known user group, sometimes you can determine the ip connection speed. (Some providers designate different subnets for dial-up / broadband connections)
