Default constructor

Access the fields within this header collection, via an iterator. Each application of the iterator returns the name of the next field type. This may then be accessed via RHTTPHeaders methods.

Obtain the named header field's value. The index of a part within the field must be specified. Parts are indexed from 0 and fields with only one part return the entire field for index 0

Obtain the value of a named parameter, associated with the named header field. An optional index to a part within the header field may be supplied, if not it is assumed that it is the first part.

Obtain an Raw representation of the named header field's value. Note that general client use of this method is strongly discouraged since it exposes the Raw representation of particular headers. However it may be needed for some cases where received headers could not be decoded by HTTP . It will normally be used internally when preparing header data to be transmitted with a request. Note that this API may not return the field values for all the headers.

Remove all the fields of this header collection

Remove, entirely, the named header field from the header collection. All its parts and associated parameters (where they exist) are also removed.

Remove a single part of a header field. Just the part and any associated paramters are removed. If this results in no parts being present in the header then it will also be removed

Setter Methods Methods for writing data. Set a named field in the header. On the first instance that this API method is used for a given field name, the first will be created. On subsequent calls, the same field will be extended to have several parts, with a new part created to hold the supplied value.

Set a named field in the header, and associate with it the supplied parameter. If the field doesn't already exist it will be created along with a parameter; if it does exist, then a new part will be created along with the parameter.

Set a named field in the header to contain the supplied Raw header data. If the header already exists then a LF and the new data will be added to the existing data. This is used to indicate that there are multiple instances of this header

Note that general client use of this method is strongly discouraged since it exposes the raw representation of particular headers. However it may be needed for some cases where headers to be transmitted have no encoding known to HTTP . It will normally be used internally when receiving data from a service provider.
