If you prefer to obtain software from respected download sites, you can visit HttpMaster Softpedia Page (4.5 star editor's review).
You can download standalone copy of documentation without installing HttpMaster (if necessary unblock chm file contained in the zip before opening it). If you have HttpMaster installed, this documentation is already on your machine and can be accessed directly from the application.
To use downloaded sample project, extract 'sample.hmpr' file contained in the zip and open it in HttpMaster. For more information about the sample project, read its description in project properties and description of each project request item in request item properties.
