A


Advanced Global CDN

Advanced Global CDN is a Managed Service that takes Pantheon's CDN offering a step forward, for customers that require unique optimizations for digital delivery at scale.

Excerpt from: Frontend Performance

Authoritative Name Server

The service that publishes your domain's DNS records

Excerpt from: Apache Solr on Pantheon

Block Caching

If you're generating a block, this will expose the block to Drupal's built-in block caching.

Excerpt from: Caching in Drupal Views

Branch

Movable pointer to a set of commits, allowing independent development and history.

Excerpt from: Multidev

C


Cache-control

This header should include a max-age that is the maximum number of seconds that the cache can be kept.

Excerpt from: Frontend Performance

Classist language

Classist language denigrates or erases the experience of those from other socio-economic classes, specifically those classes seen as "below" the speaker.

Excerpt from: Inclusive Language at Pantheon and in the Pantheon Community

Commit

Record snapshot to history.

Excerpt from: Multidev

Core

A core is a separate configuration and index using a single Solr instance. A core is created when the schema is posted. For more information, see https://wiki.apache.org/solr/CoreAdmin

Excerpt from: Apache Solr on Pantheon

D


Database

A single .sql dump that contains the content and active state of the site's configurations.

Excerpt from: Migrate to Pantheon: WordPress Site Networks

Decoupled Architecture

Decoupled Architecture is a site architecture that combines the speed and agility of static sites with the editing ease of standard-model content management systems. Web teams can use tools and frameworks specialized to their areas of expertise; Front-end Developers can use modern JavaScript-centric frameworks and libraries rather than the theming systems of older, monolithic LAMP stack systems like WordPress and Drupal.

Excerpt from: Decoupled Sites

Document

A document is similar to a database row, containing the contents of what is to be searched and whatever fields are associated with it, like title.

Excerpt from: Apache Solr on Pantheon

Excerpt from: Introduction to the Domain Name System

E


Environment

Excerpt from: Terminus Manual

EOL

F


Facet

Search facets allow search results to be filtered; examples include seeing a list of potential filters and the count of matches for each filter on the left, like Amazon product searches.

Excerpt from: Apache Solr on Pantheon

Fork

G


Gendered language

Gendered language is commonly understood as language that has a bias towards a particular sex or social gender.

Excerpt from: Inclusive Language at Pantheon and in the Pantheon Community

Excerpt from: Caching in Drupal Views

Racial language

Racial language is derogatory to people due to their ethnicity, race, or skin color. These terms, slurs, and stereotypes contributed to decades of prejudice, discrimination, and violence.

Excerpt from: Inclusive Language at Pantheon and in the Pantheon Community

Registrar

The service through which you purchase a domain name. Most registrars also offer DNS management services.

Excerpt from: Introduction to the Domain Name System

Excerpt from: Caching in Drupal Views

Repository

Centralized location of code intended for distribution.

Site Name

Machine readable, such as "your-awesome-site", either derived automatically by the platform from the site label or uniquely defined during site creation via Terminus. This value is used to construct platform domains.

Excerpt from: Terminus Manual

Site Visits

We consider a Site Visit as a 200-level (and some 300-level) response code in response to a visitor, and we identify unique consumers as a combination of user agent (device/browser) and IP address (network source), as shown in the diagram below.



Subdomain

Separate by periods (.), subdomains precede the domain name. www is the most commonly seen subdomain. Subdomains can also stack (example: www.something.example.com).

Excerpt from: Introduction to the Domain Name System

Surrogate-key-raw

Metadata including the the content IDs for what was displayed on this page. This metadata instructs this page to be cleared from cache when any of those posts are saved again. This header is only present when you specifically add a debugging header (Pantheon-Debug:1) to your request. You can use a browser extension to add the debugging header (here are some extensions for Chrome and Firefox).

Excerpt from: Inclusive Language at Pantheon and in the Pantheon Community

Visitor

A visitor is a person or device who/that receives information from the site. The platform counts each visitor once per day, regardless of the number of times they return that day or the number of pages they visit that day.


X


X-served-by

This header indicates which POP your response came from. Our primary infrastructure is in the Midwest of the United States so the first item you will probably see on this list will include "ORD" for the O'Hare airport in Chicago. If you're physically located in Austin you will also see DFW, indicating the response went from the primary datacenter to a cached copy in Chicago to a cached copy in Dallas.
