Library Databases and Systems - Known Issues

Cookies

A cookie is information stored on your computer by a website you visit. The databases accessed through the Library catalogue use cookies, so they must be enabled in your browser. Many sites report a 400 error when a cookie it's reading is corrupt or too old.

Clearing your cache

Sometimes, problems with any webpage can be solved by clearing your browser cache. 

Caching errors are most simply diagnosed by copying the URL that gives you the error and pasting it into a New Private or New Incognito window. If it works, then the issue is caching, history and/or cookies.

Clearing your cookies/cache/web history resolves a number of different issues and errors, including:

• Enable Cookies message
• Error 413 Request entity Too Large
• Error 'Too Many Redirects'
• Bad Request - Request Header or Cookie Too large
• 'The page isn't redirecting properly'
