PURL Guide

PURLs, or persistent uniform resource locators, are URLs that don’t change. OMG.LOL customers can make as many PURLs as they’d like.

What’s a PURL?

A PURL is a way to refer to something that changes (or might change) in a way that doesn’t. With a PURL, you can create an unchanging URL like you.omg.lol/joke and point it to some other URL like reddit.com/r/Jokes/comments/hexrqq/what_did_yoda_say_when_he_saw_himself_in_4k/. When people visit you.omg.lol/joke they’ll be taken to that Reddit joke page. But at any point you can change that destination URL, and make your /joke PURL go to another joke! A better one, maybe.

Why use a PURL?

There are all kinds of uses. One is as simple as the example above—a “joke of the day” where the URL never changes but the joke does. PURLs are also useful for pointing to very specific resources that don’t move often—but when they do, you’re able to update the destination URL and effectively keep the PURL accurate indefinitely.

Accessing your PURLs

By default, all of your PURLs work on two domains: omg.lol and url.lol (which is our dediated PURL service domain). This means that for every PURL you create, the following URLs will resolve to it:

  1. you.omg.lol/purl
  2. omg.lol/you/purl
  3. you.url.lol/purl

The url.lol domain exists for your convenience, in the event that your omg.lol domain is configured in such a way that you can’t use PURLs (e.g. DNS settings that point it away from our server).

PURL hit counter

Every time someone accesses your PURL, we’ll count a hit for you. You can view the total hits for each of your PURLs on your addresses’s PURLs page. We don’t track any data associated with PURL visits and respect everyone’s privacy.

Preview page

You can append /wut to any PURL to view a URL preview page, if you’d like to avoid surprises.

Do’s and Don’ts

Do make PURLs that are useful, convenient, and fun! These are harmless PURLs.

Don’t make PURLs that are spammy, point to malicious resources, or might make anyone have a bad day. These are harmful PURLs and they’re unwelcome here.

Reporting abuse

You can report abuse related to PURLs (or anything else) by emailing abuse@omg.lol at any time.
