Additionally, you can specify whether each parameter should be URL encoded.If you are not sure what this means, it is probably best to select it. This functionality is present for If this is selected, then the response is not stored in the sample result.The query string will be generated in the correct fashion, depending on the choice of "Method" you made (i.e. Also, if you are sending a file using a multipart form, the query string will be created using the multipart form specifications.See below for some further information on parameter handling.It also lets you control whether or not JMeter parses HTML files for images and other embedded resources and sends HTTP requests to retrieve them.The following types of embedded resource are retrieved: for details.The sample results have various attributes (success/fail, elapsed time, data size etc.) and can be viewed in the various listeners.
Likewise, Headers are sent for the initial request, and won't be sent for the redirect.
If you have more than one HTTP Request that needs authorizations or cookies, then add the elements to the Thread Group.
That way, all HTTP Request controllers will share the same Authorization Manager and Cookie Manager elements. Note that this applies to each wait for a response.
If you are going to send multiple requests to the same web server, consider using an HTTP Request Defaults Configuration Element so you do not have to enter the same information for each HTTP Request.
Or, instead of manually adding HTTP Requests, you may want to use JMeter's HTTP(S) Test Script Recorder to create them.
This generally occurs before the test plan starts, so it's not possible to change the settings by using the Samplers perform the actual work of JMeter.
