| address |
String |
A hostname, IPv4, or IPv6 address for the backend. This is the preferred way to specify the location of your backend. |
[optional] |
| auto_loadbalance |
Boolean |
Whether or not this backend should be automatically load balanced. If true, all backends with this setting that don't have a request_condition will be selected based on their weight. |
[optional] |
| between_bytes_timeout |
Integer |
Maximum duration in milliseconds that Fastly will wait while receiving no data on a download from a backend. If exceeded, the response received so far will be considered complete and the fetch will end. May be set at runtime using bereq.between_bytes_timeout. |
[optional] |
| client_cert |
String |
Unused. |
[optional] |
| comment |
String |
A freeform descriptive note. |
[optional] |
| connect_timeout |
Integer |
Maximum duration in milliseconds to wait for a connection to this backend to be established. If exceeded, the connection is aborted and a synthethic 503 response will be presented instead. May be set at runtime using bereq.connect_timeout. |
[optional] |
| first_byte_timeout |
Integer |
Maximum duration in milliseconds to wait for the server response to begin after a TCP connection is established and the request has been sent. If exceeded, the connection is aborted and a synthethic 503 response will be presented instead. May be set at runtime using bereq.first_byte_timeout. |
[optional] |
| healthcheck |
String |
The name of the healthcheck to use with this backend. |
[optional] |
| hostname |
String |
The hostname of the backend. May be used as an alternative to address to set the backend location. |
[optional] |
| ipv4 |
String |
IPv4 address of the backend. May be used as an alternative to address to set the backend location. |
[optional] |
| ipv6 |
String |
IPv6 address of the backend. May be used as an alternative to address to set the backend location. |
[optional] |
| keepalive_time |
Integer |
How long in seconds to keep a persistent connection to the backend between requests. |
[optional] |
| max_conn |
Integer |
Maximum number of concurrent connections this backend will accept. |
[optional] |
| max_tls_version |
String |
Maximum allowed TLS version on SSL connections to this backend. If your backend server is not able to negotiate a connection meeting this constraint, a synthetic 503 error response will be generated. |
[optional] |
| min_tls_version |
String |
Minimum allowed TLS version on SSL connections to this backend. If your backend server is not able to negotiate a connection meeting this constraint, a synthetic 503 error response will be generated. |
[optional] |
| name |
String |
The name of the backend. |
[optional] |
| override_host |
String |
If set, will replace the client-supplied HTTP Host header on connections to this backend. Applied after VCL has been processed, so this setting will take precedence over changing bereq.http.Host in VCL. |
[optional] |
| port |
Integer |
Port on which the backend server is listening for connections from Fastly. Setting port to 80 or 443 will also set use_ssl automatically (to false and true respectively), unless explicitly overridden by setting use_ssl in the same request. |
[optional] |
| request_condition |
String |
Name of a Condition, which if satisfied, will select this backend during a request. If set, will override any auto_loadbalance setting. By default, the first backend added to a service is selected for all requests. |
[optional] |
| share_key |
String |
Value that when shared across backends will enable those backends to share the same health check. |
[optional] |
| shield |
String |
Identifier of the POP to use as a shield. |
[optional] |
| ssl_ca_cert |
String |
CA certificate attached to origin. |
[optional] |
| ssl_cert_hostname |
String |
Overrides ssl_hostname, but only for cert verification. Does not affect SNI at all. |
[optional] |
| ssl_check_cert |
Boolean |
Be strict on checking SSL certs. |
[optional][default to true] |
| ssl_ciphers |
String |
List of OpenSSL ciphers to support for connections to this origin. If your backend server is not able to negotiate a connection meeting this constraint, a synthetic 503 error response will be generated. |
[optional] |
| ssl_client_cert |
String |
Client certificate attached to origin. |
[optional] |
| ssl_client_key |
String |
Client key attached to origin. |
[optional] |
| ssl_hostname |
String |
Use ssl_cert_hostname and ssl_sni_hostname to configure certificate validation. |
[optional] |
| ssl_sni_hostname |
String |
Overrides ssl_hostname, but only for SNI in the handshake. Does not affect cert validation at all. |
[optional] |
| tcp_keepalive_enable |
Boolean |
Whether to enable TCP keepalives for backend connections. Varnish defaults to using keepalives if this is unspecified. |
[optional] |
| tcp_keepalive_interval |
Integer |
Interval in seconds between subsequent keepalive probes. |
[optional] |
| tcp_keepalive_probes |
Integer |
Number of unacknowledged probes to send before considering the connection dead. |
[optional] |
| tcp_keepalive_time |
Integer |
Interval in seconds between the last data packet sent and the first keepalive probe. |
[optional] |
| use_ssl |
Boolean |
Whether or not to require TLS for connections to this backend. |
[optional] |
| weight |
Integer |
Weight used to load balance this backend against others. May be any positive integer. If auto_loadbalance is true, the chance of this backend being selected is equal to its own weight over the sum of all weights for backends that have auto_loadbalance set to true. |
[optional] |
