What is meta? ×
Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 131 Stack Exchange communities.

I work behind an really annoying firewall, and I just want the net admin to add all the SE websites to the whitelist. Right now I've lost access to Stack Overflow's authentication, but not Meta's... so I have to come here before I log in there.

It's driving me nuts. Basically I just want to add an exclusion rule for all SE domains; not only the website domains, but also the content domains such as gravatar.com, quantserve.com, the domain that holds static content, etc...

*.sstatic.net has all our static files. This is pretty much required to use the sites.

ajax.googleapis.com has JavaScript that helps the site function as expected. Pretty much required.

stackauth.com is needed for global login. Optional, but convenient if you're active on several Stack Exchange sites.

*.gravatar.com has the little icons next to people's names. Optional, but nice.

imgur.com hosts pictures that some users upload.

The other dependencies (*.quantserve.com, *.google-analytics.com) are used for our own analytics, letting us know how many visitors we get. Those are optional and the site works fine without them.

Nice clarification. Thanks. –  Tom Jun 18 '10 at 20:16
    
How will this change if a CDN is implemented? –  nhinkle May 22 '11 at 8:25
    
@nhinkle: It won't -- we're using a subdomain of sstatic.net, so "*.sstatic.net" covers that. –  balpha May 22 '11 at 9:00
    
Good to know @balpha, thanks for the info. –  nhinkle May 22 '11 at 9:17

I'm a Community Wiki answer; please update me!

The following domains (and in most cases their subdomains, e.g. *.stackexchange.com) are necessary to view Stack Exchange content and participate on Stack Exchange:

  • * ajax.googleapis.com — for some JavaScript (jQuery, …)
  • askubuntu.com — for Ask Ubuntu
  • * i.stack.imgur.com — for most user images
  • * cdn.mathjax.org — for MathJax (for sites with math formatting)
  • mathoverflow.net — for Math Overflow
  • serverfault.com — for Server Fault
  • stackoverflow.com — for Stack Overflow
  • stackexchange.com (including level 2 subdomains: *.*.stackexchange.com) — for most SE sites
  • * sstatic.net — for static content (JavaScript, CSS, images, …)
  • stackapps.com — for Stack Apps
  • superuser.com — for Super User

* Required for "normal" site usage on any site. In other words, if you just want to let your employees browse and post on Stack Overflow, but not waste time at Gaming Arqade, then you'll need to include Stackoverflow and all these dependencies.

The following additional domains are required to enable additional features:

  • stackauth.com — for global login
  • www.gravatar.com — to see users' avatars
  • *.quantserve.com, *.google-analytics.com, *.scorecardresearch.com — purely optional

You can get a complete (and always up to date) list of Stack Exchange site URLs from the API. There are wrapper libraries in many languages for reading the API.

I included grav and quant because they loaded up in the resources for the site. Mind you, so does google. –  Incognito Mar 2 '11 at 16:34

Neither one of them is in my NoScript whitelist and the sites all work fine, including seeing avatars. I have no idea what quantserve does, though. EDIT: and now I do know what quantserve does. Thanks, @Grace! –  Pops Mar 2 '11 at 16:35
