How to build a web service to detect content change(s) at an external website?
- by Global nomad
I'm researching ways to build a web service to periodically traverse a predetermined list of web pages (of another external website) to detect if a page's content has changed from
editing of the page, and
deletion of the page.
The end goal is to have this web service post push-notification events to mobile devices.
FYI, I've searched and read "Questions with similar titles" here.
Thank you for sharing your answers.
