Symptoms:
 
When viewing a webpage, an 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.
 
Possible Solutions
 
1. Checking whether it's a caching issue
 
This problem is either the new version of the webpage hasn't been published properly, or it has been, but isn't being displayed.
 
To check whether the webpage has been published:
  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 the expected new version, but the older version is still displayed when accessing via the website through an HTTP path, then it's 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's 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's 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 Internet Explorer
 
To force a refresh of the current webpage, and ignore local cached versions, press CTRL+F5.
 
Deleting Temporary Internet Files from the client PC
 
To delete Temporary Internet Files in Internet Explorer (Instructions are given for Internet Explorer 7):
  1. Run Internet Explorer.
  2. From the toolbar, Tools > Internet Options.
  3. On the General tab, under 'Browsing history', click 'Delete...'.
  4. On the 'Delete Browsing History' dialog, under 'Temporary Internet Files', click 'Delete Files...', and agree to any prompt to proceed.
  5. When complete, close the 'Delete Browsing History' and 'Internet Options' dialogs.
  6. Close Internet Explorer.
  7. Re-open Internet Explorer, and try the webpage again.
Configure caching in Internet Explorer
 
Internet Explorer may display a webpage from the copy held in its cache, rather than the copy on the web server. This assumes that the cached copy matches that stored on the web server, but it may not.
 
To configure Internet Explorer's caching behaviour:
(Instructions are given for Internet Explorer 7)
  1. Run Internet Explorer.
  2. From the toolbar, Tools > Internet Options.
  3. On the General tab, under 'Browsing history', click 'Settings'.
  4. In the 'Temporary Internet Files and History Settings' dialog, under 'Temporary Internet Files', set 'Check for newer versions of stored pages' from 'Automatic' to 'Every time I start Internet Explorer' (if this doesn't work, then try the 'Every time I visit the webpage' setting).
  5. Close the 'Temporary Internet Files and History Settings' and 'Internet Options' dialogs.
  6. Close Internet Explorer.
  7. Re-open Internet Explorer, and try the webpage again.
Configure caching in IIS on the web server
 
To configure caching behaviour on the web server:
  1. On the web server, run Internet Information Services (IIS) Manager.
  2. In the left-hand pane, expand 'Web Sites', then the site that contains the site that is being configured (probably 'Default Web Site').
  3. Still in the left-hand pane, right-click on the desired site > Properties.
  4. In the site Properties dialog, click on the 'HTTP Headers' tab.
  5. Check the 'Enable content expiration' box.
  6. Set 'Web site content should' to 'Expire after', say, 5 minutes.
  7. Click OK to close the Properties dialog.
  8. In the left-hand pane of the 'Internet Information Services (IIS) Manager' dialog, click on '<computer name> (local computer)'.
  9. From the menu bar, Action > All Tasks > Restart IIS....
  10. Close Internet Information Services (IIS) Manager.
Applies to:
  • Internet Explorer
  • IIS (Internet Information Services)
