llLoadURL() truncates URLs at 255 characters, which is a problem in use cases such as passing an http-in URL to a remote system through use of llLoadURL for callback usage. URLs passed back by http-in are around 81 characters, and 107 characters once URL-encoded. Assuming another 80-ish characters for the basic URL of the target system, this leaves 70-ish characters for any other data being passed through the URL, which isn't that hard to exhaust (particular if, for example, you're passing an avatar key in the URL as well). Could we please have an increased acceptable length for llLoadURL() to resolve this? Unless you have any actual proven security or performance issues, I'd suggest uncapping the URLs (and leaving LSL memory requirements to act as a sanity check). I've attached a simple LSL script which grabs an http-in URL and shows it, plus it's URL-encoded equivalent, along with lengths.
