Sampler is used to simulate a user operation, and send a request receiving server response data to the server, like the LoadRunner Vuser; i.e. HTTP request HTTP protocol Vuser
basic skills
Automatically redirects: selected said, when the HTTP request if the response is a 301/302, Jmeter automatically redirected to a new page corresponding to, but not recorded redirected
Request and response content, only GET and HEAD requests to use automatic redirection
Follow the redirect: automatic redirect a second election, selected by default, represents the response is 301/302, it will automatically jump to the target page, the initial response as redirection and further
Additional samples appear. The value of the URL and data fields from the parent sampler sampler last non redirector. However, the parent sampler and the number of bytes taken interval comprising
, The latency value is taken from the sampler in response to a first
Use keep Alive: When this option is selected, and the target server use between jmeter Keep-Alive HTTP communication mode is selected by default. In the default
Under HTTP implementation it does not work, because the connection is not reused under user control. But in Apache HttpComponents HttpClient it works
Use of POST multipart / from-data: using the multipart / HTTP from-data transmission or application / x-www-form-method
