- ns_respond - Build a complete response
- ns_respond ?-status status? ?-type type? ?-string string | -file file | -fileid fileid? ?-length length? ?-headers setId?
- ns_respond returns a complete response to the client using exactly one of -string, -file or -fileid as the body. After the command completes the connection is returned to the driver thread to be closed or monitored for keep-alive and the calling connection thread continues to execute code. Just like with ns_return, all the normal compression, encoding, chunking, etc. processing applies, unless otherwise noted below.
- -status status
- The HTTP status code. Default 200.
- -type mimetype
- The mime-type of the response body. Default */*.
- -headers setid
- A set of headers which will replace any pending headers for the response.
- -string body
- The Tcl string to send as the response body. The body may be encoded into an apprpriate character set if required by the client and server settings.
- -file filepath
- The file identified by the given pathname will be sent as the response body. No character set conversion will be done.
- -fileid channel
- length bytes of the given channel will be used as the response body. No character set conversion will be done.
- -length length
- Specifies the number of bytes to send from the channel. Required if using -fileid
- Using ns_respond, it's easy to do an HTTP redirect:
set headers [ns_set new myheaders] ns_set put $headers location http://www.aolserver.com ns_respond -status 302 -type text/plain \ -string "redirection" -headers $headers
