+\constfunc{int}{GetResponse}{\void}

 \membersection{wxHTTP::GetInputStream}\label{wxhttpgetinputstream}
 
 \func{wxInputStream *}{GetInputStream}{\param{const wxString\&}{ path}}
 
-Creates a new input stream on the 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 doesn't deal with it. Other functions like StreamSize and
-Tell aren't available for the moment for this sort of stream.
-You will be notified when the EOF is reached by an error.
+Creates a new input stream on the specified path. Notice that this stream is
+unseekable, i.e. SeekI() and TellI() methods shouldn't be used.
+
+Note that you can still know the size of the file you are getting using 
+\helpref{wxStreamBase::GetSize()}{wxstreambasegetsize}. However there is a
+limitation: in HTTP protocol, the size is not always specified so sometimes
+\texttt{(size\_t)-1} can returned ot indicate that the size is unknown. In such
+case, you may want to use \helpref{wxInputStream::LastRead()}{wxinputstreamlastread} 
+method in a loop to get the total size.
 
 \wxheading{Return value}
 
-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

+Returns the initialized stream. You must delete it yourself once you

+destroyed. 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

 \func{void}{SetHeader}{\param{const wxString\&}{ header}, \param{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 \it{header} and the content by \it{h\_data}.
+name is specified by {\it header} and the content by {\it h\_data}.
