Description of configuration options for [app-proxy-server] in proxy-server.conf

Configuration option = Default value	Description
account_autocreate = false	If set to 'true' authorized accounts that do not yet exist within the Swift cluster will be automatically created.
allow_account_management = false	Whether account PUTs and DELETEs are even callable
auto_create_account_prefix = .	Prefix to use when automatically creating accounts
client_chunk_size = 65536	Chunk size to read from clients
conn_timeout = 0.5	Connection timeout to external services
deny_host_headers =	No help text available for this option.
error_suppression_interval = 60	Time in seconds that must elapse since the last error for a node to be considered no longer error limited
error_suppression_limit = 10	Error count to consider a node error limited
log_handoffs = true	No help text available for this option.
max_containers_per_account = 0	If set to a positive value, trying to create a container when the account already has at least this maximum containers will result in a 403 Forbidden. Note: This is a soft limit, meaning a user might exceed the cap for recheck_account_existence before the 403s kick in.
max_containers_whitelist =	is a comma separated list of account names that ignore the max_containers_per_account cap.
max_large_object_get_time = 86400	No help text available for this option.
node_timeout = 10	Request timeout to external services
object_chunk_size = 65536	Chunk size to read from object servers
object_post_as_copy = true	Set object_post_as_copy = false to turn on fast posts where only the metadata changes are stored anew and the original data file is kept in place. This makes for quicker posts; but since the container metadata isn't updated in this mode, features like container sync won't be able to sync posts.
post_quorum_timeout = 0.5	No help text available for this option.
put_queue_depth = 10	No help text available for this option.
read_affinity = r1z1=100, r1z2=200, r2=300	No help text available for this option.
recheck_account_existence = 60	Cache timeout in seconds to send memcached for account existence
recheck_container_existence = 60	Cache timeout in seconds to send memcached for container existence
recoverable_node_timeout = node_timeout	Request timeout to external services for requests that, on failure, can be recovered from. For example, object GET. from a client external services
request_node_count = 2 * replicas	replicas Set to the number of nodes to contact for a normal request. You can use '* replicas' at the end to have it use the number given times the number of replicas for the ring being used for the request. conf file for values will only be shown to the list of swift_owners. The exact default definition of a swift_owner is headers> up to the auth system in use, but usually indicates administrative responsibilities. paste.deploy to use for auth. To use tempauth set to: egg:swift#tempauth each request
set log_address = /dev/log	Location where syslog sends the logs to
set log_facility = LOG_LOCAL0	Syslog log facility
set log_level = INFO	Log level
set log_name = proxy-server	Label to use when logging
sorting_method = shuffle	No help text available for this option.
swift_owner_headers = x-container-read, x-container-write, x-container-sync-key, x-container-sync-to, x-account-meta-temp-url-key, x-account-meta-temp-url-key-2, x-container-meta-temp-url-key, x-container-meta-temp-url-key-2, x-account-access-control	These are the headers whose conf file for values will only be shown to the list of swift_owners. The exact default definition of a swift_owner is headers> up to the auth system in use, but usually indicates administrative responsibilities. paste.deploy to use for auth. To use tempauth set to: egg:swift#tempauth each request
timing_expiry = 300	No help text available for this option.
use = egg:swift#proxy	Entry point of paste.deploy in the server
write_affinity = r1, r2	This setting lets you trade data distribution for throughput. It makes the proxy server prefer local back-end servers for object PUT requests over non-local ones. Note that only object PUT requests are affected by the write_affinity setting; POST, GET, HEAD, DELETE, OPTIONS, and account/container PUT requests are not affected. The format is r<N> for region N or r<N>z<M> for region N, zone M. If this is set, then when handling an object PUT request, some number (see the write_affinity_node_count setting) of local backend servers will be tried before any nonlocal ones. Example: try to write to regions 1 and 2 before writing to any other nodes: write_affinity = r1, r2
write_affinity_node_count = 2 * replicas	This setting is only useful in conjunction with write_affinity; it governs how many local object servers will be tried before falling back to non-local ones. You can use '* replicas' at the end to have it use the number given times the number of replicas for the ring being used for the request: write_affinity_node_count = 2 * replicas
