GET HTTP Request in Scripting

Ignition
1

Hi,
I am working on a demo project to read variable value from a PLC using HTTP GET Request. I am reading the value of variable var3 using this script:
result = system.net.httpGet(“http://192.168.1.220/dir/cgi-bin/readVal.exe?@GV.var3”)

I am getting proper response with variable value to result for first time. But when I send the request again, I am not getting the new value but instead I am getting the last received value.

Anyone can help on this to sort out it.

Thanks in advance.

Try setting the useCaches parameter to false.

system.net.httpGet(url = "...", useCaches = false)

This works…
Thanks for the quick support…
