log exception when bad link detected

[VladaHejda]

When 404 occurred after pass through an anchor with referer on site self, it is probably bad link inside application self and not user's typo or search engine wrong index - it might be worth to send report.

👎 too smart

[VladaHejda]

and what about log that exception when just any referer exists?

[enumag]

Why log entire exception? We can just add the referer information to access.log.

[VladaHejda]

but that 404 may be an error in application.. and who reads access log...

[enumag]

I do. And to prevent errors in application I use INVALID_LINK_EXCEPTION.

[VladaHejda]

what if programmer self throws BadRequestException because of invalid input parameter:

function actionDefault($number) {
    if ($number > 3) {
        throw new BadRequestException;
    }
}

but <a n:href="this number => 5">link</a> is not invalid link...

[enumag]

That's exactly why I use this approach.

IMHO logging of 404 can be removed, it is usually done (in better way) by web server.

[VladaHejda]

@enumag: actually I don't see how that approach can solve the issued problem.

Is there any way to merge this or should we close this?
