I have two ISPs /two routers on my LAN with Windows boxes. Switching default gateway (per PC) works fine, so I can choose my outgoing traffic from particular PC to be initiated from whichever ISP I want.
Is there any way to perform some specific HTTP request through **non-default gateway (while all other requests /browsing etc goes normally through default gateway); ideally with some cmd-line tool (like WGET or CURL)? I tried to search through their manuals, but couldn't find it. Alternatively, some solution in PHP would be fine too.
