When you GET a resource from a TiddlyWeb server, you must tell the server what data format you would like to receive. There are two ways to do this:

• Specifying a format extension
• Setting an HTTP header
  
  

Select by format extension

To select type by format extension, make a request of the form:

Where format is as defined below.

format	MIME type requested	MIME type returned
txt	text/plain	text/plain
html	text/html	text/html
json	application/json	application/json
wiki	text/x-tiddlywiki	text/html

Select by Accept header

Instead of adding the .format extension, you can set the HTTP Accept header to one of the MIME types from the above table. In this case, your request is simply:

Ambiguous Requests

If both .format and an Accept header are given, the .format takes precedence, assuming it is valid.
