RFID RC522 seems to not send GET data to a xampp web server via W5100 Ethernet

my problem uid not sent web server on pc serially printed , client certified connected. [outputs "connected" , ip printed] not reflect on db. i'm using xampp, firewall off, ip both correct. port 80 , manual encoding of argument working, localhost/add_data_php?rfid=12345678 [12345678 reflect on db] maybe because needs delay? or on or off of ss pins of each? appreciated.

the "counter" , "first" variables used condition whenever card gets detected, that's way data sent server. seems work fine serially, gets pass through code whenever card gets detected. not reflect on db. manage save in db "dummy" number , and in 1 execution only, setup , not on loop. please hellppp thanks.

   client.print("host: ");

unless pc serving multiple domains, highly unlikely, part not needed.

what log files on server say?

why not reading server response? not reading reply leave socket open. 4 times , toast.
