Sushila Burgess commented on WICKET-6929:
-----------------------------------------
I am sorry that I did not use the quick start. I only originally identified
what I think is the problem by slowly whittling away file after file and
functionality after functionality from our real application. The remaining code
is extremely simple now. There is no database, no need to know anything at all
about our real application, and the error is all demonstrated within 2 pages:
# Login Page
# Welcome Page
I would really appreciate it if you could have a look at the application as it
is. However, please let me know if this is really impossible.

> Key: WICKET-6929
> URL: https://issues.apache.org/jira/browse/WICKET-6929
> Project: Wicket
> Issue Type: Bug
> Components: wicket-core
> Affects Versions: 9.5.0
> Environment: Windows 10 Enterprise, JDK 11.0.7, NetBeans 11.3 and
> Payara 5.201
> Reporter: Sushila Burgess
> Priority: Minor
> Labels: WebClientInfo
> Attachments: icase_debug.zip
>
> Original Estimate: 24h
> Remaining Estimate: 24h
>
> We found that in Wicket 9, an intermittent error occurred which forced our
> users
> to log in twice, even though they were definitely already correctly logged
> in
> and their session had not expired. (This error did not occur in Wicket 1.5.)
> We have found that this error is associated with checking WebClientInfo
> properties. In the course of redirection to and from BrowserInfoPage, it
> seems
> as if the user's login credentials somehow get lost.
> We have found a work-round, which is to check WebClientInfo properties before
> login. However, the disadvantage of this is that every single user sees the
> following message for perhaps a second as they first log in:
> "If you see this, it means both JavaScript and meta-refresh are not support
> by
> your browser configuration. Please click this link to continue to the
> original
> destination."
> We have attempted to reproduce this error in a simple quick-start
> application.
> We can reproduce it reliably on first opening *Chrome* or *Edge* on
> *localhost*.
> In the current, simple application, we cannot reproduce it when visiting a
> URL
> with a fully qualified domain name, but it did occur, intermittently, in the
> full-scale application.
> The quick-start application is attached as a zip file. Please see the
> README.txt of that application for a few more details.
