[AWS] Possible 'cookie' problem (AWS.Client.Parse_Header) ?

[Charles Darcy]

Hi,

    Should the AWS.Client.Parse_Header procedure set the
Connection.Cookie when the parsed cookie is a null string (ie there is
no cookie) ?

   -- Existing code.
   --
   procedure Parse_Header (...) is
      ...
   begin
      ...
      Connection.Cookie := +Response.Header
                              (Answer, Messages.Set_Cookie_Token);
      ...
   end Parse_Header;


    I'm using AWS to fetch pages from a site which requires a login.
When I login, the site sends me a cookie. This cookie is added to the
headers of any subsequent GET's to the site, to verify the access.

    My problem is that after I receive the cookie, the site sends
further messages which contain no cookie. In this case, Parse_Header
still sets Connection.Cookie to a null string. Any further GET's to the
site will now fail, since the verifying cookie is not present.


    I changed the code to:


   procedure Parse_Header (...) is
      ...
   begin
      ...
      declare
         The_Cookie : Unbounded_String 
                    := +Response.Header (Answer,
                                         Messages.Set_Cookie_Token);
      begin
         if The_Cookie /= "" then
            Connection.Cookie := The_Cookie;
         end if;
      end;
      ...
   end Parse_Header;


    The Connection.Cookie is now only updated if a new cookie exists.
These changes fix my problem, but being new to AWS/networks/cookies, I'm
not sure if they are correct in every case ?

    Any advice will be appreciated.


regards,

Charlie.
