Hi

 I use a Form based authentification in web.xml :
[...]
<login-config>
<auth-method>FORM</auth-method>
 <realm-name>Authentication Area</realm-name>
 <form-login-config>
 <form-login-page>/login.jsp</form-login-page>
 <form-error-page>/login_failed.jsp</form-error-page>
 </form-login-config>
</login-config>
 [...]

in login.jsp :
[...]
<form method="GET" action="j_security_check">
<input type="text" name="j_username">
<input type="password" name="j_password">
</form>
[...]

authentification works great but after, if i click on the "Back"  button of
my browser to go back on the login page
and i try the authentification again, Tomcat launch a HTTP 404 error on
/j_security_check
 (page refresh don't change anything)

in access.log (i protect /pages/* and login form is in /login.jsp):

10.20.0.7 - - [10/Sep/2002:11:01:15 -0500] "GET /pages/home.jsp HTTP/1.1"
302 764
10.20.0.7 - - [10/Sep/2002:11:01:15 -0500] "GET /login.jsp HTTP/1.1" 200
7070
10.20.0.7 - - [10/Sep/2002:11:01:21 -0500] "GET
/j_security_check?j_username=bob&j_password=bob HTTP/1.1" 302 764
10.20.0.7 - bob [10/Sep/2002:11:01:23 -0500] "GET /pages/home.jsp HTTP/1.1"
200 5018

here, all is ok , i'm authentified as bob (i think that 302 HTTP return code
is a good thing ? servlet redirection ??)
now i click on back button and attempt to re-authentifiate bob and ...

10.20.0.7 - bob [10/Sep/2002:11:01:29 -0500] "GET
/j_security_check?j_username=bob&j_password=bob HTTP/1.1" 404 734

404 error ...

Do you have a solution ?

Thanks a lot.
