You are developing an ASP.NET Core website that uses Azure FrontDoor. The website is
used to build custom weather data sets for researchers. Data sets are downloaded by users as Comma Separated Value (CSV) files. The data is refreshed every 10 hours.
Specific files must be purged from the FrontDoor cache based upon Response Header values.
You need to purge individual assets from the Front Door cache.
Which type of cache purge should you use?
- A . single path
- B . wildcard
- C . root domain
Suggested Answer: A
Explanation:
These formats are supported in the lists of paths to purge:
✑ Single path purge: Purge individual assets by specifying the full path of the asset (without the protocol and domain), with the file extension, for example, /pictures/strasbourg.png;
✑ Wildcard purge: Asterisk (*) may be used as a wildcard. Purge all folders, subfolders, and files under an endpoint with /* in the path or purge all subfolders and files under a specific folder by specifying the folder followed by /*, for example, /pictures/*.
✑ Root domain purge: Purge the root of the endpoint with "/" in the path.
