- Related: Load Balancing Virtual Server, Load Balancing Method
A Citrix ADC feature that ensures requests from the same client are directed to the same backend service for a period. It can be based on source IP, cookies, or other identifiers.
- SSL Offloading
- Related: SSL Bridge, Certificate, SSL Profile
The process of decrypting SSL/TLS traffic at the Citrix ADC appliance and forwarding it to backend servers in plaintext. This reduces the processing load on servers and enables inspection.
- SSL Bridge
- Related: SSL Offloading, Certificate
A Citrix ADC configuration where SSL/TLS traffic is passed through the appliance without decryption. The client establishes an SSL session directly with the backend server.
- Certificate
- Related: SSL Offloading, Certificate Authority (CA), SSL Profile
A digital document used to authenticate the identity of a server or client in SSL/TLS communications. On Citrix ADC, certificates are bound to virtual servers to enable SSL offloading.
- Certificate Authority (CA)
- Related: Certificate, Certificate Signing Request (CSR)
An entity that issues and signs digital certificates. Citrix ADC can use certificates signed by a trusted CA or act as a CA for internal certificates.
- Certificate Signing Request (CSR)
- Related: Certificate, Certificate Authority (CA)
A block of encoded text generated on the Citrix ADC appliance that contains information about the entity requesting a certificate. It is submitted to a CA to obtain a signed certificate.
- SSL Profile
- Related: SSL Offloading, Certificate
A Citrix ADC configuration object that defines SSL/TLS parameters such as protocol versions, ciphers, and session settings. It is bound to virtual servers to control SSL behavior.
- Global Server Load Balancing (GSLB)
- Related: GSLB Site, GSLB Service, DNS Policy
A Citrix ADC feature that distributes traffic across multiple data centers or sites based on health, proximity, and load. It uses DNS to direct clients to the best available site.
- GSLB Site
- Related: GSLB, GSLB Service
A logical representation of a data center in a GSLB configuration. Each site contains local Citrix ADC appliances and services that participate in global load balancing decisions.
- GSLB Service
- Related: GSLB, GSLB Site, Monitor
A Citrix ADC entity that represents a resource (such as a virtual server) at a GSLB site. It includes the IP address, port, and health monitoring settings for that resource.
- DNS Policy
- Related: GSLB, GSLB Service
A Citrix ADC policy that controls how DNS queries are handled, including GSLB decisions. It can match on domain name, source IP, and other criteria to select a GSLB method.
- High Availability (HA)
- Related: HA Node, Failover, HA Synchronization
A Citrix ADC configuration where two appliances are paired in an active-passive setup to provide redundancy. If the primary fails, the secondary takes over to maintain service availability.
- HA Node
- Related: High Availability (HA), Failover
A Citrix ADC appliance that is part of a high availability pair. Each node has a role (primary or secondary) and communicates with its peer to monitor health and synchronize state.
- Failover
- Related: High Availability (HA), HA Node
The process by which a secondary Citrix ADC node takes over the primary role when the primary node fails or becomes unavailable. Failover can be automatic or manual.
- HA Synchronization
- Related: High Availability (HA), HA Node
The process of keeping configuration and state consistent between Citrix ADC nodes in a high availability pair. It ensures that the secondary node can take over seamlessly.
- Authentication Policy
- Related: Authorization Policy, Authentication Server, Session Policy
A Citrix ADC policy that defines how users are authenticated before accessing resources. It can specify authentication methods such as LDAP, RADIUS, or SAML, and is evaluated in order.
