Static URL's for HTTP-In Service (No longer working)

This article is out of date! This script relies on a defunct external service.

Service:

LSL Redirect, is a project made to provide an easy solution for HTTP-In temporal limitation in LSL (Second Life). The system is designed to handle static URLs (permanent links) and redirect them to a specific HTTP-In URL. This HTTP-In URL can be updated or removed from Second Life if needed.

This service can be used only by LSL scripts and only for HTTP-In URLs, this is not a redirection service like 'tinyurl' or 'tr.im'.

API

With our API, you have an ID, wich is your link and a CODE. The code is used as password to identificate who is requesting changes in the ID. With the code you can update the URL or remove the ID if needed.

To keep your ID up-to-date, you have to do a frequent update, the http-in changes when the region restart, object cross-sim, object rez, object reset. Make sure you do an update each time the http-in url changes. Also, make sure you store the CODE and ID in a notecard, do not use temporal variables to store this information or you wont be able to use them.

More info about the service and its API here.
