Description

type should be a MIME type (see ns_guesstype manual page for a list).

status is a three-digit number fitting the pattern below:

1xx	Informational - Not used, but reserved for future use.
2xx	Success - The action was successfully received, understood, and accepted.
3xx	Redirection - Further action must be taken in order to complete the request.
4xx	Client Error - The request contains bad syntax or cannot be fulfilled.
5xx	Server Error - The server failed to fulfill an apparently valid request.

Some common status values and their meanings are:

200	OK	403	Forbidden
201	Created	404	Not Found
202	Accepted	405	Method Not Allowed
203	Provisional Information	406	None Acceptable
204	No Content	407	Proxy Authentication Required
300	Multiple Choices	408	Request Time-out
301	Moved Permanently	409	Conflict
302	Moved Temporarily	410	Gone
303	Method	500	Internal Server Error
304	Not Modified	501	Not Implemented
400	Bad Request	502	Bad Gateway
401	Unauthorized	503	Service Unavailable
402	Payment Required	504	Gateway Time-out

ns_return sends back both the headers and the string.

ns_returnadminnotice performs the same function as ns_returnnotice, except that it appends a line with a link to "mailto:serveradministrator" based on the virtual server parameter "WebMaster".

ns_returnbadrequest returns a 400 status code and a formatted HTML message containing the reason text.

ns_returnerror wraps the text msg in some html and returns that to the client.

ns_returnfile sends back the headers and the contents of the file.

ns_returnforbidden returns a 403 status code.

ns_returnfp first sends the appropriate headers. Next, it writes out the contents of file from the current file position until the end of the file.

ns_returnnotfound returns a 404 status code.

ns_returnnotice wraps the text msg and longmsg in some html and returns that to the client.

ns_returnredirect returns a redirect to the passed in location.

ns_returnunauthorized returns a 401 status code.
