B4R Question Getting same response with http post method with my Esp8266 12E

[embedded]

I am trying to on off a led from my webpage...so I write a PHP script which make changes in a JSON file "lightn" or "lightff" when I press on or off button from my webpage.
Here every thing is fine and works smoothly.
When I read JSON file using esp8266 every minute....I get response .But this response is repeated again and again..while I make change in JSON file by pressing button...which is also confirm by reading JSON file from browser.
If I power off esp8266...then after power up first response is ok...next response after a minute...same.
I think may be some problem with response cache which is set to 5000..How we clear this response cache when we start post method again.
Please help...

Did you test by iexplorer? Maybe IIS cached the file, so it's not refreshed.

In this case write a page in which you open and read json and send back.

I read json file with chrome browser...its response is normal everytime...only issue with esp8266...first time reading ok...then same response....again and again

Job.Response as far as I remember reports status of request. To tead text use job.gettext instead.

job.gettext attribute is not available....

 

[tigrot]

Forgive me, use job.getstring or job.getstring2...

You should use Job.Response: https://www.b4x.com/android/forum/threads/module-rhttputils2-http-client.74785/#content
