Understand the problem

The HTML pages generated by applications usually contain dynamic elements, that is to say components whose values vary from one call to the next. Typically, these include unique identifiers that cannot be replayed "as is", and which must be managed individually.

When dynamic parameter handling fails:

NeoLoad automatically handles the most common parameters, such as the Framework .Net __VIEWSTATE parameter. However, NeoLoad cannot automatically handle parameters that are specific to an application. They need to be handled individually, that is to say by placing an extractor on the value returned by the server and injecting the extracted value into the appropriate requests.

NeoLoad provides the necessary tools to handle a dynamic parameter manually. For more information, see Handle an application dynamic parameters<in_pdf_tuto>.
