Fetch

The Fetch script command sends an http POST or GET request to the current IP variable, according to the current variables on the Fetch panel (IP, Timeout, Sitename, Page, Port, and basic authentication username:password). Should a reply be received, a parsing script will be run associated with the current Sitename and Page.

Syntax:	Fetch				Comment
Example:	Fetch				Fetch the currently selected IP, Sitename, Page, and Port with currently selected timeout
Associated command may be bound to Fetch to set any or all current choices
Example:	Assign	IP	=	192.168.2.252	Associated command to set IP destination
	Assign	Timeout	=	5	Associated command to set Timeout
	Assign	HTTPMethod	=	GET	Associated command to set Method to GET
	Assign	HTTPSitename	=	"Well Monitor"	Associated command to set Sitename
	Assign	HTTPPage	=	jsdata.txt	Associated command to set Page
	Assign	HTTPPort	=	80	Associated command to set Port
	Assign	HTTPUsername:Password	=	admin:pw	Associated command to set basic authentication username & password
	Fetch				Ping 192.168.1.1 with 5sec timeout
Associated command may be bound to Fetch to set or add lines to the header
Example:	Assign	HTTPHeader	=	expression	Associated command to set header to expression text
	Add Line	HTTPHeader	=	expression	Associated command to add expression text to header along with line terminating CR,LF
	Fetch				fetch
Associated command may be bound to Fetch to set or add lines to the body, such as for form parameters using the POST method. (Form parameters would be appended to the Page variable when using the GET method.)
Example:	Assign	HTTPBody	=	expression	Associated command to set body to expression text
	Add Line	HTTPBody	=	expression	Associated command to add expression text to body along with line terminating CR,LF
	Fetch				fetch

Notes:

• Initiating a fetch automatically clears the current HTTPReplyCode
• Receipt of final tcp Reply automatically sets HTTPReplyCode to the 3 digit number found at the start of the reply such that the various common reply codes can be tested by If script command
• Receipt of final tcp Reply automatically sets MessageDelayTime variable with the elapsed time in msec (an http fetch can require multiple tcp response packets depending upon its size)
• Timeout of tcp Reply automatically sets MessageDelayTime variable to -1
