HTTP is one of the available protocols.

Engine-specific headers, e.g. params, must be prefixed with X-Autoserver-, e.g. X-Autoserver-Params.

The following HTTP request headers have specific interpretations:

• Content-Type and Accept set the format and the charset like the format and charset query variables do.
• Accept-Encoding sets the response's compression like the compress query variable does.
• Content-Encoding sets the request payload's compression like the compress query variable does.
• Prefer: return=minimal sets the silent argument to true. Same thing for the HEAD method.
• X-HTTP-Method-Override: METHOD overrides the current HTTP method    (which must be POST)

The following HTTP response headers might be set, depending on the response:

• Content-Type, Content-Length, Vary, Allow, X-Response-Time
• when using REST and the response is paginated, a Link header will be set with rel first, last, prev and/or next. The header contains the full URI to retrieve the first, last, previous or next batch, as opposed to metadata.pages which only contain the cursor tokens.

Error responses

The HTTP status code of error responses depends on the error type. See the previous link for a list of the status codes used.
