Ns conn

NAME

ns_conn - Find information about the current HTTP connection.

SYNOPSIS

ns_conn option ?arg arg ...?

DESCRIPTION

This command is used to retrieve various pieces of information about a connection.

The legal options (which may be abbreviated) are:

• ns_conn authpassword

Returns the decoded user password from the authorization data.

• ns_conn authuser

Returns the decoded user name from the authorization data.

• ns_conn close

Closes the connection so the script (or ADP) can do any time-consuming processing without making the client wait. If you use ns_conn close in an ADP, streaming should be turned on before closing the connection (i.e. <SCRIPT RUNAT=SERVER STREAM=ON>) or nothing will get sent out at all.

• ns_conn content ?offset? ?length?

Returns the content of the HTTP request body, optionally a substring of that content starting at offset and extending length characters.

• ns_conn contentlength

Returns the number of bytes in the content passed in.

• ns_conn driver

Returns the name of the module (nssock or nsssl) that is acting as the communications driver for this connection.

• ns_conn form

Returns any submitted form data as an ns_set. This form data may have been submitted with a POST or appended to the URL in a GET request. Note: ns_conn form is not suitable for multipart formdata file upload widgets.

• ns_conn headers

Returns all the header data as an ns_set. The keys of the ns_set represent the field names. The case of the returned field names depends on the HeaderCase configuration parameter. By default, HeaderCase is "Preserve", which means case is preserved.

• ns_conn host

Returns the host part of the URL in the HTTP request.

• ns_conn isconnected

Returns 1 if you're in a connection thread, and you are therefore allowed to make calls to ns_conn. It returns 0 if you're not in a connection thread (such as when you're in a schedule procedure) and you are not allowed to make calls to ns_conn.

• ns_conn location

Returns the location string for this virtual server in the form: protocol://hostname[:port].

• ns_conn method

Returns the HTTP method, e.g. GET.

• ns_conn outputheaders

Returns an ns_set containing the headers that will be sent out when a result is returned to the client. This ns_set can be manipulated like any other ns_set. You can also use this command to write to the set of output headers. For example: ns_set put [ns_conn outputheaders] key value.

• ns_conn peeraddr

Returns the IP address of the client, i.e. the "other side" of the HTTP connection. The IP address is returned in the form of a string separated with periods (e.g., 155.164.59.75).

• ns_conn port

Returns the port specified explicitly in the URL of the HTTP request. If the browser does not explicity send the ":port" part of the URL, the port number returned will be 0.

• ns_conn protocol

Returns the protocol of the URL in the HTTP request (usually unspecified).

• ns_conn query

Returns any query data that was part of the HTTP request.

• ns_conn request

Returns the HTTP request line as presented by the client, e.g. GET / HTTP/1.1.

• ns_conn url

Returns the URL of the HTTP request. This is the portion of the request after the hostname, for example [ns_conn url] on http://aolserver.com/ returns /index.adp.

• ns_conn urlc

Returns the number of elements (delimited by `/') in the URL of the HTTP request.

• ns_conn urlv

Returns a list containing the pieces of the URL delimited by `/'.

• ns_conn version

Returns the version of the HTTP request. This is usually 1.0 or 1.1.
