Abstract:
In a computing environment connected to a network, computer readable code stored on a storage medium readable by a computer system in said environment for measuring round-trip latency between a client and a server without requiring a client-side proxy presence, comprising:computer readable code means for receiving, at said server from said client, a first client request for a first Uniform Resource Locator (URL); computer readable code means for determining, responsive to receiving said first client request, that said round-trip latency between said client and said server is to be measured; and computer readable code means for measuring said round-trip latency, further comprising: computer readable code means for storing a first time at which said first client request was received; computer readable code means for responding to said first client request with a redirection response, wherein said redirection response specifies a second URL; computer readable code means for receiving, from said client, a second client request for said second URL, wherein said second client request is received at a second time; computer readable code means for computing a difference between said second time and said first time, wherein said difference represents said round-trip latency; and computer readable code means for sending to said client, responsive to receiving said second client request, information associated with said first URL.
