Browser Cache Issues
Belden Horizon Data Operations and Belden Horizon Data Manager applications use a web browser as their main interface. For optimized loading, web browsers keep a cache of files and images for recently visited websites. This avoids having to download the pages each time you visit a page.
This optimization can sometimes cause problems when the browser reads from its cache instead of downloading the latest page. This can cause unexpected behavior such as the following:
- The page looks partially loaded.
- The page looks like it has loaded but the page has strange or unusual formatting.
- Images on the page are in the wrong places.
- Strange login and license activation issues.
