## Summary
When uploading or downloading an updated ebook from SD/WebUI/OPDS with
same the filename the `.crosspoint` cache is not cleared. This can lead
to issues with the Table of Contents and hangs when switching between
chapters.
I encountered this issue in two places:
- When I need to do further ePub cleaning using Calibre after I load an
ePub and find that some of its formatting should be cleaned up. When I
reprocess the same book and want to place it back in the same location I
need a way to invalidate the cache.
- When syncing RSS feed generated epubs. I generate news ePubs with
filenames like `news-outlet.epub` and so every day when I fetch new news
the crosspoint cache needs to be cleared to load that file.
This change offers the following features:
- On web uploads, if the file already exists, the cache for that file is
cleared
- On OPDS downloads, if the file already exists, the cache for that file
is cleared
- There's now an action for `Clear Cache` in the Settings page which can
clear the cache for all books
