Old version of map displayed in webpage

Symptoms

When viewing a webpage, the new version of the page is not displayed as expected.

Following a website publication, the changes made to the Visio-based process map may not be apparent in the associated webpage.

Cause

The new version of the webpage has not been published properly or it is not being displayed.

Solution

To check whether the webpage has been published properly:

1. Open Windows Explorer.
2. Browse to the HTML file on the webserver using Windows Explorer.
3. Double-click on the HTML file to open it.

If the webpage is not the expected version, you will need to ensure that the correct version of the Visio file is present and then republish.

If the webpage is the expected new version, but the older version is still displayed when accessing via the website through an HTTP path, then it is a caching issue.

This problem may be resolved by reconfiguring the caching behaviour of the browser on the client PC, or the web server. It is recommended that the following steps are tried in the order given, only proceeding to a subsequent step if the issue is not resolved by a preceding one. It may be necessary to experiment with different settings to give the best result. For example, if it is found that the problem required configuring content expiration on the web server, then it may be better to restore the browser's default caching behaviour.

Refreshing Page in the browser

To force a refresh of the current webpage, and ignore local cached versions, press CTRL+F5.

Deleting Temporary Internet Files from the client PC

This will depend upon the browser. Use the browser Help, an Internal Search or your IT department to find out how to do this for your browser.

Configure caching in the browser

If this a persistent problem, you may need to configure the cacheing behaviour of the browser. For example, Internet Explorer allows you to specify when it should check for newer versions of stored pages.

Use the browser Help, an Internal Search or your IT department to find out how to do this for your browser.
