Lslurl
Introductory
LSLurl (domain do not response atm) is a Dynamic DNS service focused primarily on the in-world script event, http_request (Article: LSL_http_server). LSLurl provides an extensively featured and flexible API system and the solution to URL Lifetime Limitations. LSLurl also provides an online dynamic storage database. Domains and their content can be created, updated, and deleted via in-world scripts. Users of LSLurl are provided with numerous options for customizing their domains. Optionally, API keys are provided to utterly secure users' domains from unwanted access.
Features
- Optional API-key security (Viewing and/or editing)
- Permanent domains
- Optional temporary domains (6 hour prune interval)
- Create, edit, delete, and search domains via in-world scripts
- Online storage database
- Automatic URL Parsing ("\n", spaces, ANSII characters, etc.)
- Web-based control panel & account management
- Domain types: URL (redirects) and DATA (stores data)
- Unlimited domains
- Unlimited subdomains
Future features:
- Firewall (IP filtering, blocking, etc.)
- Custom sub-domains. Example: http://yourname.lslurl.com/domain
Getting Started
IMPORTANT: Closed beta.
To begin using LSLurl, visit an in-world terminal. By clicking the in-world terminal, you will be given a password to use at LSLurl. Log in with your Second Life username and the password given.
Creating a domain
To create a domain, you must first be logged in. Click the 'Create a new domain' link as shown in the image.
Creating a domain is essentially direct. Simply fill out the creation form and click 'Create'. Sub-domains created via in-world scripts will inherit the settings as the main domain by default.
Note: API keys are limited to 32 characters, and the characters: 'a-z', '0-9', '-', and '_'.
Domain Types
Domains are either one of the two types: DATA or URL. DATA is used for text storage. The domain will return the text of the domain's value. URL is used for in-world http servers as a static URL proxy (or redirect) and solving the URL Lifetime Limitation.
In-world Usage
The LSLurl API system is composed of two scripts. The LSLurl API script, and the core script that handles all of the HTTP-related functions.
Script API
LSLurl API v0.26 by The Wikifoo <lsl>//LSLurl API v. 0.26 BETA
string MY_DOMAIN = "test"; string MY_APIKEY = ""; string MY_TYPE = ""; //URL or DATA. By leaving this blank you will not update the type.
string lslurl_cmd(string command,string domain,string value,string apikey,string type) {
/* SHORT DESCRIPTION:
response: response acts like a callback identifier which is used to identify the response from your requests
command: UPDATE_VALUE, CREATE_SUB, GET_VALUE, FIND_DOMAIN, DELETE_DOMAIN ...
url: the domain you're trying to perform an action to. (only the domain name, i.e., 'test' (without the quotes)
subdomains works too, however, you will have to use, 'test.subdomain' (again, without the quotes)
value: whatever value you want to set in your domain
apikey: your private apikey - only required if you have "require apikey" in read- or writemode.
type: set your urls type to DATA or URL. leaving it blank will not update the type.
