HTTP Echo

An extremely plain HTTP request echo service. Without ads, not so HTML, for programmatic usage.

Formats

A variety of response formats are supported. It may be specified as a parameter named echoFormat (query or form parameter) or by the standard HTTP Accept header.

• as param works in a browser: http://echo.dirkraft.com?echoFormat=application/json
• with accept header with curl: curl -H"Accept: application/json" http://echo.dirkraft.com

Supported formats:

• application/json
• text/html
• text/plain (default)
• text/xml

Deployment on Heroku

The deployment there involves a heroku-managed proxy that routes traffic to the actual application and the Internet. As a consequence proxy forwarding headers are received by HTTP Echo. These headers are filtered out of the response normally, but can be included with the parameter and value echoAllHeaders=true (query or form parameter).
