What's New in Witango 5

This information is detailed in the What's New Documentation mentioned above,in most cases your application will run without issue. However, the issues which if applicable that should be addressed are:

1. HTTP headers

   HTTP headers must be a complete HTTP response header. Partial headers will now throw a http 500 error on the server. An example of a complete header is below:
   

   <@ASSIGN request$httpHeader "HTTP/1.1 <@HTTPSTATUSCODE> <@HTTPREASONPHRASE><@crlf>Date: <@CURRENTTIMESTAMP FORMAT='datetime:http'><@crlf>Server: Witango 5.0.1.062<@crlf>MIME-Version: 1.0<@crlf>Content-Type: text/html<@crlf><@crlf>">
   
   Two new tags exist to assist <@HTTPSTATUSCODE> and <@HTTPREASONPHRASE>.

2. Local scope is now known as REQUEST scope

   The scope which used to be known as 'local', in Witango 5 is known as 'request'. The change in name was made because Request better reflects that the lifespan of the variables in this scope is limited by the duration of the current http request. The old name is still supported so that both names, Local and Request, may be considered as aliases. The user should however be aware that when the Witango 5 Editor opens the taf files all 'local' scoping will be made 'request' and therefore will exhibit different behaviour when run on the Tango2000 server.

3. Variables which are NOT scoped

   The default scope for the Witango Server has been changed from 'user' to 'request'. If you application relies on the default scope being USER then the witango.ini file should be changed such that the parameter DEFAULTSCOPE is set to USER.

Server Admin Application

What used to be known as 'config.taf' is now known as the Witango 5.5 Admin Application. It can be downloaded at this link.
