I will appreciate any help or pointers regarding this question.
When I get error message, say, “server not found” for a URL like this:
The URL address does not change. It still shows the URL of the requested site, but the content is an error message.
Where is this message retrieved from? if I want to customize it if it occurred using page-mod
for example, I need to know the URL for this error. But, in the error pages case, I do not know their URL.
Are there any methods other than page-mod
to customize an error page before it appears on the tab? in a way that distinguish error types? Any suggestions?
