Static Content Not Displayed When Refreshing A Page With CTRL-R Using ORDS Standalone (Doc ID 2405137.1)

ORDS 18.1.1 version

When using CTRL-R or F5 to refresh the page the images / static content stop displaying. When hitting CTRL-R or F5 again the static content comes back.

The following error can be see and one can see that the following error occurs in the access.log if using a web server or in the browser console.

ERROR
-----------------------
 When we type CTRL-R or F5 to refresh a page, static content (/i/) is not displayed.

In the access_log file we see entries like the following for static content, error code 404:

IP# - - [10/May/2018:14:38:32 +0000] "GET /i/app_ui/css/Core.min.css?v=5.1.4.00.08 HTTP/1.1" 404 257

If we type CTRL-R or F5 again the static content comes back.

• The CTRL-F5 refresh command always works.
• ORDS Deployed in WLS always works when using CTRL-R.
• ORDS Standalone with Chrome Browser also works consistently when using refreshing the page with CTRL-R.

Steps to Reproduce

The issue can be reproduced at will with the following steps in Firefox or IE 11:
1) Login in APEX Builder (can be any page that display images)

2) Type CTRL-R
The page is not re-displayed correctly (no-images),and  one can see 404 errors for css and js files in the browser console (when Developer Tools is activated with F12 on most browsers.)

3) Type CTRL-R again
The page is almost displayed correctly but some 404 errors are still seen.

4) Type CTRL-F5
Using CTRL-F5 always works, and all images are seen.
