The forum software doesn't support ghost topics afaik. And leaving posts that just say "moved to" just fill up the forum with unnecessary topics. It's true that it can confuse some people when their post suddenly "disappears" on them, but the forum doesn't get enough new topics that it is all that difficult to find the moved topic. Also, moved topics are marked as unread even if you're read it in the previous forum, so it is even easier to find.
That said, maybe moderators can consider leaving a PM to the poster when moving a message to the appropriate forum? Just a thought.
As far as your question... you'll need a sockread event and just check if the line matches what you're looking for. As long as there is only one line that starts with <span class="hps">, you can check if the text read in using /sockread
<span class="hps">* iswm %var and then do whatever you want with it. Any socket script can be used for examples of how to use sockread and check if the text matches something you're looking for.
Regarding HTTP/1.1, you need to include HTTP/1.0 or HTTP 1.1 in your script. Often, 1.0 works better than 1.1. However, your error about not being connected suggests that there is another problem. I can't test anything at work, but maybe someone else can take a look for you.
