Quick SLurl FAQ

What is a SLurl™?

A Second Life URL (SLurl) is a teleport link to a location in Second Life.

Think of it this way: you can't get to a webpage without knowing its URL (Uniform Resource Locator), commonly called a "hyperlink" or simply "link". Just like your web browser has bookmarks, in Second Life, we have SLurls. Since our virtual world is three-dimensional, SLurls contain a Region name and 3 positioning coordinates within that region.

How do I use a SLurl?

Just like a hyperlink! It's easy:

Click this example SLurl.
On the page it takes you to, click Visit this location in Second Life.
Even if you don't have Second Life, there are instructions to join us.

How do I make a SLurl?

Move your avatar to where you want to create the SLurl.
Click the place name in the location bar (near the top of the Viewer window) to convert it to a SLurl. It'll look like http://maps.secondlife.com/secondlife/Here/128/128/44.
Right-click and Copy the SLurl while it's selected, or use Ctrl+V.
Paste the SLurl where you want it.

Tip: Pasting a SLurl into text chat (or an instant message) makes it appear in a abbreviated form that can be clicked on, like any other hyperlink. For example, http://maps.secondlife.com/secondlife/Here/128/128/44 appears as Here (128,128,44).

What's the difference between a SLurl and a landmark?

SLurls and landmarks serve the same purpose: addresses of Second Life places.

The difference is that while a SLurl is simply a text link, a landmark is an inventory item type which can only be used inside of SL.

How do I convert a landmark to a SLurl (and vice-versa)?

Converting any landmark to a SLurl is easy.

Click the Places sidebar tab.
Right-click a landmark and select Copy SLurl.

The SLurl is now ready to be pasted as described above.

To convert a SLurl to a landmark:

Click or otherwise use the SLurl to get to its location.
Select World menu > Landmark This Place.

What's the difference between maps.secondlife.com and slurl.com ?

Both domains are valid for SLurls. These point to the same inworld place:

However, maps.secondlife.com is more context-rich, meaning it's a friendlier introduction for someone who's never used Second Life before. If you're using SLurls on the broader web, we recommend using maps.secondlife.com

Technical SLurl details

The maps.secondlife.com and slurl.com websites are implemented using the Second Life Map API. If you have a website, you can use it as well to embed Second Life maps on your pages, in the same way you can embed Google Maps.

How it works

Use a SLurl to direct people to inworld locations like this:

Create a SLurl, either within the Viewer (as detailed above) or using SLurlBuilder (which as of January 2011, hasn't changed in years).
Share the SLurl with a person who you want to tell about something in Second Life.
They click the SLurl. It's a web link like any other.
They'll see a http://SLurl.com page and more info, if you provided it.

If the person doesn't have Second Life

The SLurl page (either http://maps.secondlife.com or http://slurl.com) displays a link to join Second Life.

From the signup up page, they can quickly register, download the Second Life Viewer, and log in. When they first log in, they will initially arrive at the destination specified by the SLurl, not the default start location on Welcome Island. A quick tutorial opens upon their initial arrival to help them get started.

If the person has Second Life

If the Second Life Viewer is not already running, it'll start.

When they log in, they'll be at the location specified by the SLurl.
If they're already logged in, the Place Profile opens in the Second Life Viewer's sidebar.
When they click the Teleport button in this window, they'll be instantly teleported to the location specified by the SLurl. Alternatively, they can click Map to display the target location on the World Map, or close the sidebar if they don't want to be teleported.

Expected behavior

On Windows, a SLurl opens the most recently installed Viewer.

There isn't an immediate way to change which Viewer launches SLurls, so if you have the current released Viewer and a Release Candidate, whichever was installed most recently will start. You can change this by reinstalling the Viewer.

Every SLurl page's SLurl title and Teleport Now button link to a "secondlife://" address, which is an URI scheme which opens Second Life. This is different from the familiar "http://" used for webpages.

Tip: The reason why it's advantageous to post "http://" SLurls instead of direct "secondlife://" addresses in webpages is for the benefit of people who don't have Second Life yet. Giving them the latter doesn't work, since it depends on SL being installed. A SLurl serves as a friendly intro to tell them about Second Life as-needed and where they'll be going.

Constructing SLurls

The basic format for a SLurl is:

http://SLurl.com/secondlife/<region>/<x>/<y>/<z>?param=value&param=value...

Where:

<region> is the name of the destination Region
<x> and <y> are the east/west and north/south coordinates of the destination; <z> is the vertical (height) coordinate.
The ? and the parameters that follow it are optional and provide additional information to be displayed in the SLurl.com page; see Query string parameters for more information.

Query string parameters

Note: In Linden Lab's official showcasing of SLurls, this has somewhat been deprecated by the Destination Guide.

You can use the SLurlBuilder to make the following easier.

Supply SLurl query string parameters to set the window title, image, and text. Parameters are just name=value pairs. Just like a standard URL, precede the first parameter pair with a question mark (?), and all subsequent parameter pairs with an ampersand (&).

Parameter	Description	Example
title	Title text to display in the teleport window.	To specify the window title "Come to My Island!" use title=Come%20To%20My%20Island For example: http://slurl.com/secondlife/Ahern/50/50/50/?title=Come%20To%20My%20Island
img	URL of image to display in teleport window. Must be a complete (absolute) URL, and preferably a small image of 256x256 pixels or less.	To display this example image, use img=http://slurl.com/examples/forsale.png For example: http://slurl.com/secondlife/Ahern/50/50/50/?img=http://SLurl.com/examples/forsale.png
msg	Message text to display in the teleport window	To specify the message text "Your text here", use msg=Your%20text%20here For example: http://slurl.com/secondlife/Ahern/50/50/50/?msg=Your%20text%20here.

Shortening SLurls

SLurls with string parameters can get quite long and ugly. This makes them difficult to paste into places like emails, which may have line breaks that mangle the SLurl.

You can use a 3rd-party URL-shortening service to condense a SLurl and make it easier to share. There are dozens of these out there, including:

bit.ly - Twitter's default, one of the most popular. Has stats-tracking.
Snurl - No relation to SLurl.
TinyURL - One of the first.

If you have a webserver with a customizable redirect, you can do something similar.
