Head Method

Sends a HEAD request to the server.

Syntax

int Head(const QString& qsUrl);

Remarks

HEAD is very similar to GET, with the only difference being that only the headers (but not the content) is returned.

HEAD is often use to retrieve the parameters of the resource, such as its size and modification date. If the request is successful, those details will be available via ResponseParameters and ResponseHeaders properties. Otherwise, an exception will be thrown, and the error details published in StatusCode and ReasonPhrase properties.

Note that any parameters you intend to pass to this method should be properly encoded before this method is called.

Error Handling

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
