Context

Before configuring an HTTP test instance, configure an HTTP server and ensure reachable routes between the HTTP client and the HTTP server.

Through an NQA HTTP test, you can obtain the response speed in three phases:

DNS resolution time: indicates the time taken to resolve the HTTP server domain name into its IP address. During this process, the NQA client sends a DNS request to the DNS server. The DNS server resolves the domain name of the HTTP server to an IP address and returns a DNS response.
TCP connection setup time: indicates the time spent in setting up a TCP connection between the NQA client and the HTTP server through three-way handshake.
Transaction time: It is a period from the time the client sends the Get or Post packets to an HTTP server to the time the Echo packet sent by the client reaches the HTTP client.

The NQA client also functions as the HTTP client. Perform the following steps on the NQA client.
