char array wont display what it reads from the connected descriptor
 
This is my code. accept returns the connected descriptor but in the read function the buffer(array) contains some garbage values. I am trying to capture the request made by the browser. I have configured the proxy so it will connect to the desired port. please help

Initialize the buffer with " "

char buff[1501] = " ";
