Browser Issues?

Clearing your browser's cache, history and/or cookies is not only good, regular maintenance for your computer but can also fix many common issues with some web-based applications (webmail, Canvas, Banner, etc.) when they won't load or close mysteriously mid-session. This frustrating situation can occur if the files in your browser cache get corrupted or just stop working.

Please follow the directions on this page for your specific operating system and browser version to clear the cache, cookies and/or history. You may also contact helpdesk@156china.com for assistance.

What is a browser cache?

Each time you access a file through your web browser, the browser caches (i.e., stores) it. By doing this, the browser doesn't have to newly retrieve files (including any images) from the remote web site each time you click Back or Forward.

You should periodically clear the cache to allow your browser to function more efficiently.

What are browser cookies?

A cookie is a file created by a web browser, at the request of a web site, that is then stored on a computer. These files typically store user-specific information such as selections in a form, shopping cart contents, or authentication data.

Browsers will normally clear cookies that reach a certain age, but clearing them manually may solve problems with web sites or your browser.

What is a browser history?

A browser's history is a log of sites that you visit. When you press a browser's Back button, you are moving back one entry in the history log.

Browsers will normally clear their history at regular intervals, but you may want to clear it manually for privacy reasons.
