Requesting feed content unnecessarily critical
This app is unnecessarily re-requesting feed content from websites without waiting until there's actually new content published.
Why it's a problemThe unnecessary traffic wastes a website's resources that can be used for its other site visitors.
What it means for usersWebsites are likely to limit this app from accessing feed content, causing feeds to not update properly or stop working entirely.
How to fix it
The application needs to be updated to
wait
until the max-age of
Cache-Control header expires before re-requesting
feed content or properly implement
conditional requests.
Not using updated feed locations critical
When a feed from a website is moved to a new location, the website informs the application where the feed has been moved to. However, instead of using the new locations of feeds, this application continuously tries to request feeds from their old locations.
Why it's a problemIt causes websites to use more computer resources than necessary to forcibly redirect the application to the rightful place over and over again.
What it means for usersFeeds will stop working or become fully inoperable when a website blocks the application due to this behavior.
How to fix itWhen a feed has been relocated to a new URL, the application should use the new URL and cease attempting to request feed content from the old one.
