Does HttpMaster support simple ad hoc internet requests without opening new project?
Yes. HttpMaster includes 'Basic request tool' for ad hoc execution of internet requests; it is also possible to create new project from you ad hoc requests for more advanced work. HttpMaster also has the ability to open particular project request items in 'Basic request tool'.

What is HttpMaster project file used for?
HttpMaster project file is simply a container for your project definition and request items. It has a 'hmpr' extension and is stored internally in XML format. For example, when you work with Microsoft Word, you can store your document as 'docx' file to be able to open it later. When you work with HttpMaster, you store your project as 'hmpr' file to be able to open it later.

Can HttpMaster project file be transferred to another machine and opened there?
HttpMaster project file (*.hmpr) created on one machine can be copied to another machine and opened there with HttpMaster tool. Keep in mind that you cannot open project file with the older HttpMaster version if it was created with the newer version of the tool.

Can HttpMaster execute internet requests against any web server?
HttpMaster can execute requests against any web server no matter on which operating system or platform the web server is running.

Does HttpMaster support https requests?
Yes.

Does HttpMaster support any global data definition?
Yes. You can define global URL and global query string and use them with every request item. This enables you, for example, to quickly switch host of your REST/API URL paths; if you have defined request item's URL as relative URL in HttpMaster, you can simply change global URL data and immediately execute against the same internet resources located on another host.

Does HttpMaster support authentication?
Yes. You can use default credentials (credentials of the current Windows user) or network credentials (username, password, and domain).

What are parameters used for?
Parameters are very useful if you would like to execute multiple requests to the same internet resource, but with some slight difference, for example, different value of query string parameter for each request. Parameters of various data types and generation types can be defined in project properties and then used in every project request item.
Using parameters inside request item definition will also affect execution count of the request item, for example, if you have included parameter with five possible values, its execution count will automatically change to 5 and executing this item will produce five requests.
Using parameters inside request item is the only way to change execution count value of request item.

What are validations used for?
You can define validations in project properties and then use them with request items to define advanced logical validation expressions. HttpMaster will evaluate this expressions during execution and will display successful and failed executions based on the validation expression result. For example, you can define one validation for particular phrase in the response body and one validation with the range of response time. You can then combine these two validations in logical expression with AND operator and HttpMaster will validate request item's executions according to this logical expression.

What is request chaining used for?
Request chaining can be very handy if you would like to extract some piece of data from the previous request and use it with the next request. In such a way, you can execute multiple http requests that are otherwise independent in a single execution batch and assure that every request uses some data from the previous request.

How HttpMaster supports upload of various data types? Does it support 'multipart/form-data'?
HttpMaster supports upload of string data, upload of the specified file as binary array, and multipart form data upload of data and files. With these three types you can simulate practically any possible upload. HttpMaster also supports parsing of existing HTML content to automatically build request body for particular content type.

Does HttpMaster have any support for project execution automation?
Yes, you can use HttpMaster command line interace.

HttpMaster is all about REST, but can I also test SOAP web services with it?
Since SOAP is actually a special form of XML, you can also call SOAP methods exposed via http and view their responses.
However, HttpMaster does not support some advanced features, like WSDL parsing to extract SOAP methods.

Is it possible to use Telerik Fiddler with HttpMaster?
Yes. Open HttpMaster settings and specify Fiddler as a proxy (enter http://127.0.0.1:8888 for proxy address). Httpmaster will now route all traffic through Fiddler.

What is pure execution?
Pure execution does not store internal execution data on the disk so response data is not available for review. If response data is not important for your scenario, then this type of execution can be useful because it will complete faster and won't consume any disk space.
You can permanently enable pure execution for the project in project options. In such a case, response data will never be stored; even with regular execution types response data won't be available for review.
