Not really. I have no strong opinion on the benefit of limiting number/size. Stefan limited the number/size at the receiving end and made receiving end die with its message. I was merely trying to tweak the arrangement so that the sending end can complain with its own message, possibly in its own language, especially because it was unclear to me if the die() message on the receiving end would always go back to the sending end correctly. > But this comes with a > downside: the server doesn't get to send an error message about > where > the maximum number of push options can come from (e.g., with a link to > a page where the limit can be adjusted, or with an explanation of when > clients tend to run into this problem and what they should do > instead). Hmm, interesting point. That would be better told by the receiving end, as the way to configure it (if offered) would be different from installation to installation. > So I'd like to propose an alternative.
