Default:yes
Section:projects.cache

Type:boolean
Default:no
Section:projects.cache
Key:insecure
Env:QGSRV_CACHE_INSECURE

TRUST_LAYER_METADATA

Trust layer metadata. Improves layer load time by skipping expensive checks like primary key unicity, geometry type and srid and by using estimated metadata on layer load. Since QGIS 3.16.

Type:boolean
Default:no
Version Added:1.4
Section:projects.cache
Key:trust_layer_metadata
Env:QGSRV_TRUST_LAYER_METADATA
Alternate name:QGIS_SERVER_TRUST_LAYER_METADATA

DISABLE_GETPRINT

Don’t load print layouts. Improves project read time if layouts are not required, and allows projects to be safely read in background threads (since print layouts are not thread safe).

Section:projects.cache
Key:disable_getprint
Env:QGSRV_DISABLE_GETPRINT
Alternate name:QGIS_SERVER_DISABLE_GETPRINT

CACHE_PRELOAD_CONFIG

Path to configuration file for preloading projects. The file must have one project uri per line. Each uri is similar to the project uri passed in the ‘MAP’ query parameter of OWS requests. Preloaded projects are stored in a static cache, i.e they are not subject to lru eviction.

Type:path
Version Added:1.4
Section:projects.cache
Key:preload_config
Env:QGSRV_CACHE_PRELOAD_CONFIG

CACHE_DISABLE_OWSURLS

Disable ows urls defined in projects. This may be necessary because Qgis projects urls override proxy urls.

Section:projects.cache
Key:disable_owsurls
Env:QGSRV_CACHE_DISABLE_OWSURLS

CACHE_FORCE_ETAG

Force etag header even if ‘TRUST_LAYER_METADATA’ is not set. By default etags are set only when ‘TRUST_LAYER_METADATA’ is set because capabilities rely only on qgis project data and not on the underlying layer data.

Type:boolean
Default:no
Version Added:1.7.13
Section:projects.cache
Key:force_etag
Env:QGSRV_CACHE_FORCE_ETAG

CACHE_DEFAULT_HANDLER

Set the default handler for MAP parameters

Type:string

Default:*
Section:projects.cache
Key:allow_storage_schemes
Env:QGSRV_CACHE_ALLOW_STORAGE_SCHEMES

CACHE_CHECK_INTERVAL

Set the time interval in seconds between two check for invalidation/refresh of the cache content. If set to a value > 0 then the cache is checked for invalidation/refresh asynchronously every seconds defined by the option. If set to 0 (or negative value), the cache is checked for invalidation synchronously at each request. When set to 0 with slow projects to load, user may experience latency, so it is recommended to use asynchronous check with such projects in conjunction with a static cache.

Type:int
Section:projects.cache
Key:refresh_interval
Env:QGSRV_CACHE_CHECK_INTERVAL
