What does .ac extension refer to?

I visited Avis.com, and I notice the web pages have *.ac extension. Not familiar with this type--what language or framework is this? This something Python-related?

Thanks.

  • My guess is that it's Struts 1, an old Java web framework that is usually used with the .action suffix, but this isn't fixed, and .ac may be an abbreviation of that.

    This is consistent with the server name. Sun ONE 6 is a very old appserver product, long since obsolete, but it's of a similar age to Struts.
