I am using Tomcat 5.5.17 on Windows.
I have a problem setting a 408 error-page in my web.xml on form based
authentication.
I am using servlet spec defined authentication for my webapp:
<login-config>
<auth-method>FORM</auth-method>
<realm-name>Authentication</realm-name>
<form-login-config>
<form-login-page>/login.jsp</form-login-page>
<form-error-page>/error.jsp</form-error-page>
</form-login-config>
</login-config>
Step 1) In a web browser, load the login.jsp page
Step 2) Let the web browser sit on the login page for the period of time
that would expire the users session (30 mins by default)
Step 3) Click submit to send the authentication username/password.
The result of this is, not surprisingly, an error. However, the error
varies by web browser:
Firefox 2 gives a browser error:
"The connection was reset
The connection to the server was reset while the page was loading.
* The site could be temporarily unavailable or too busy. Try again in
a few
moments.
* If you are unable to load any pages, check your computer's network
connection.
* If your computer or network is protected by a firewall or proxy,
make sure
that Firefox is permitted to access the Web."
Internet Explorer 6 gives a tomcat error:
"HTTP Status 408 - The time allowed for the login process has been exceeded.
If you wish to continue you must either click back twice and re-click the
link you requested or close and re-open your browser"
So my first question: why is Firefox not displaying the 408 error?
Next, I add an error-page element to my web.xml:
<error-page>
<error-code>408</error-code>
<location>/408.html</location>
</error-page>
Then, follow the same 3 steps from above, and I would expect Firefox to
display the same browser error, but IE should display my 408.html page.
Firefox does display the same "The connection was reset" error, however, IE
displays a new error:
"The page is currently unavailable
Due to current high demand, the page you are looking for cannot be delivered
right now.

Please click the Refresh button, or try again later.
HTTP Error 408 / 409 - Not acceptable / Resource conflict
Internet Explorer"
So my second question: why is the error-page 408.html that is defined in my
web.xml, not being picked up and displayed to the browser?
Thanks for reading all of this,
