I had a simple use case. I wanted to detect the city of the visitor’s IP (e.g. New York, London, St. Louis, etc.) - for a specific URL only i.e. our homepage - and either add/to replace the value within a tag identified with a unique ID on that URL’s payload.
13,000 businesses worldwide are eliminating chaos in their business processes (including London).
That last bit would be:
<span id="unique_city_here">(including yours)</span>
How would I achieve this via a CF worker?
