Method HttpMessage() :addParameter() Foundation

The method :addParameter() adds a HTTP parameter to the parameter list along with its value. Existing values are preserved, which means that if a parameter named <cName> already exists, the value specified in <cValue> is appended to this parameter's value list.

For adding a parameter with multiple values to the parameter list, an array of values can be assigned to the <aValues> parameter. In this case, the values in the array elements are added to the value list of the HTTP parameter in one go, instead of having to calling :addParameter() repeatedly.

HTTP parameters are transferred as part of the query string. The methods :addParameter(), :delParameter(), :getParameter(), :getParameters() and their respective :set..() counterparts allow direct and easy manipulation of this part of the HTTP query string. Use the method :getQueryString() for obtaining a reference to the complete string.
