The HTTP Protocol

Build HTTP Services in DataFlex


The HTTP Handler is the newest of the three different end points that connect the DataFlex Web Application Server with the Microsoft Internet Information Server (IIS). 

The older end points are…

  • Classic ASP: calls are made to DataFlex Web Apps from ASP scripts
  • Web Services hander: supports remote procedure implementation via SOAP and JSON

With the HTTP Handler all processing is done in DataFlex code, which provides full control over the whole process. The way the HTTP Handler is bound to the to specific URLs in an application is very flexible and can work with chunks of binary data.  The HTTP Handler can be used to easily build powerful HTTP services that use REST, JSON, HTML or XML.
