Q. Does the WIZ1xxSR serial to Ethernet module product range support HTTP GET & HTTP POST?

I require both HTTP GET & HTTP POST capability for an upcoming company project.

WIZ1xxSR just forwarding data from serial to ethernet(or from ethernet to serial).
It does not process the data by itself.
So, You can send&receive the HTTP packet via WIZ1XXSR.
But It does not support HTTP by itself.
