int GetResponse() const
Returns the HTTP response code returned by the server. Please refer to the RFC 2616 for the list of the responses.
wxInputStream * GetInputStream(const wxString& path)
Creates a new input stream on the specified path. You can use all except the seek functionality of wxStream. Seek isn't available on all streams. For example, HTTP or FTP streams don't deal with it. Other functions like Tell and SeekI aren't available for the moment for this sort of stream. You will be notified when the EOF is reached by an error.
You can know the size of the file you are getting using wxStreamBase::GetSize(). But there is a limitation: as HTTP servers aren't obliged to pass the size of the file, in some case, you will be returned 0xfffffff by GetSize(). In these cases, you should use the value returned by wxInputStream::LastRead(): this value will be 0 when the stream is finished.
Returns the initialized stream. You will have to delete it yourself once you don't use it anymore. The destructor closes the network connection. The next time you will try to get a file the network connection will have to be reestablished: but you don't have to take care of this wxHTTP reestablishes it automatically.
void SetHeader(const wxString& header, const wxString& h_data)
It sets data of a field to be sent during the next request to the HTTP server. The field name is specified by header and the content by h_data. This is a low level function and it assumes that you know what you are doing.
wxString GetHeader(const wxString& header)
Returns the data attached with a field whose name is specified by header. If the field doesn't exist, it will return an empty string and not a NULL string.
The header is not case-sensitive: I mean that "CONTENT-TYPE" and "content-type" represent the same header.
