All geek questions in one place

Need PHP or Java code to use multiple Internet connections.

I have a machine with a Linux CentOS distribution that has more than one Internet connection available at a time.

I am trying to write PHP code that will do the following:

  • Make an HTTP request to a specific URL "for example google.com", but through a specific Internet connection.
  • Perform the above for several Internet connections at the same time (this means that several processes will be executed, each of which will have HTTP requests through a specific connection).

Note that internet connections are ppp0, ppp1 and ppp2.

Here is the result of "ifconfig":

Here is the result of the route command:

Anyone with ideas on how this might work?
