SID-02368: Save script can only be called with the post method.Raw edit

Status:	Asked	TWiki version:	6.1.0	Perl version:	5.6.1

Hello Some users have complained about the message

Attention

The save script can only be called with the POST method. Example:

This comes after clicking on Save from a normal Raw edit session. The problem is hard to re-produce but is annoying for the users.

The Edit session's form has method=post defined so I think that the error message is wrong.

I suspect a memory issue with the server but I would appreciate any feedback if anyone has experienced this in the past

Regards

Pete

Discussion and Answer

Update:

The error message is correct. When this problem occurs the user's browser has lost the sessions information and requests these from another server. That server replies with a GET message.

We can re-produce the problem by deleting the browser cookies.

I'm not sure why this happens to some users at random moments.

Update:

After looking more closely at how people work there are several scenarios for causing the above:

• The CommentPlugin is used in a public page. Same thing for the ActionTrackerPlugin
• A user uses the browser cache to return to an old edit session.

In these cases the user is no longer logged in. So TWiki asks for credentials from the SSO server which returns the GET and hence the error.

The error message isn't so helpful. Any thoughts on the best workaround for such cases?
