Use production logging¶
Logging may visibly affect the performance of your server. High logging levels are often necessary to track down issues, but by default you should run with low levels. (You can switch the logging levels while GeoServer is running.)
You can change the logging level in the Logging Profile. You will want to choose the
PRODUCTION logging configuration, where only problems are written to the log files.
Set a service strategy¶
A service strategy is the method in which output is served to the client. This is a balance between proper form (being absolutely sure of reporting errors with the proper OGC codes, etc) and speed (serving output as quickly as possible). This is a decision to be made based on the function that GeoServer is providing. You can configure the service strategy by modifying the
web.xml file of your GeoServer instance.
The possible strategies are:
Serves output right away. This is the fastest strategy, but proper OGC errors are usually omitted.
Stores the whole result in memory, and then serves it after the output is complete. This ensures proper OGC error reporting, but delays the response quite a bit and can exhaust memory if the response is large.
A balance between
Personalize your server¶
This is isn’t a performance consideration, but is just as important. In order to make GeoServer as useful as possible, you should customize the server’s metadata to your organization. It may be tempting to skip some of the configuration steps, and leave in the same keywords and abstract as the sample, but this will only confuse potential users.
Fill out the WFS, WMS, and WCS Service Metadata sections (this info will be broadcast as part of the capabilities documents)
Serve your data with your own namespace (and provide a correct URI)
Remove default layers (such as
Configure service limits¶
Make sure clients cannot request an inordinate amount of resources from your server.
Set the WMS request limits so that no request will consume too much memory or too much time
Set security for data modification¶
GeoServer includes support for WFS-T (transactions) by default, which lets users modify your data.
If you don’t want your database modified, you can turn off transactions in the WFS settings. Set the Service Level to
Basic. For extra security, we recommend any database access use datastore credentials providing read-only permissions. This will eliminate the possibility of a SQL injection (though GeoServer is generally not vulnerable to that sort of attack).
If you would like some users to be able to modify data, set the service level Service Level to
Complete) and use Service Security to limit access to the WFS.Transaction operation.
If you would like some users to be able to modify some but not all of your data, set the Service Level to
Complete), and use Layer security to limit write access to specific layers. Data security can be used to allow write access based on workspace, datastore, or layer security.
Cache your data¶
Server-side caching of WMS tiles is the best way to increase performance. In caching, pre-rendered tiles will be saved, eliminating the need for redundant WMS calls. There are several ways to set up WMS caching for GeoServer. GeoWebCache is the simplest method, as it comes bundled with GeoServer. (See the section on GeoWebCache for more details.) Another option is TileCache.
Caching is also possible for WFS layers, in a very limited fashion. For DataStores that don’t have a quick way to determine feature counts (e.g. shapefiles), enabling caching can prevent querying a store twice during a single request. To enable caching, set the Java system property
org.geoserver.wfs.getfeature.cachelimit to a positive integer. Any data sets that are smaller than the cache limit will be cached for the duration of a request, which will prevent the dataset from being queried a second time for the feature count. Note that this may adversely affect some types of DataStores, as it bypasses any feature count optimizations that may exist.
Disable the GeoServer web administration interface¶
In some circumstances, you might want to completely disable the web administration interface. There are two ways of doing this:
Set the Java system property
GEOSERVER_CONSOLE_DISABLEDto true by adding
-DGEOSERVER_CONSOLE_DISABLED=trueto your container’s JVM options
Remove all of the
Disable the Auto-complete on web administration interface login¶
To disable the Auto Complete on Web Admin login form:
Set the Java system property
geoserver.login.autocompleteto off by adding
-Dgeoserver.login.autocomplete=offto your container’s JVM options
If the browser has already cached the credentials, please consider clearing the cache or form data after setting the JVM option.
In order to prevent clickjacking attacks GeoServer defaults to setting the X-Frame-Options HTTP header to SAMEORIGIN. This prevents GeoServer from being embedded into an iFrame, which prevents certain kinds of security vulnerabilities. See the OWASP Clickjacking entry for details.
If you wish to change this behavior you can do so through the following properties:
geoserver.xframe.shouldSetPolicy: controls whether the X-Frame-Options filter should be set at all. Default is true.
geoserver.xframe.policy: controls what the set the X-Frame-Options header to. Default is
SAMEORIGINvalid options are
These properties can be set either via Java system property, command line argument (-D), environment variable or web.xml init parameter.
OWS ServiceException XML mimeType¶
By default, OWS Service Exception XML responses have content-type set to
In case you want it set to
text/xml instead, you need to setup the Java System properties:
-Dows10.exception.xml.responsetype=text/xmlfor OWS 1.0.0 version
-Dows11.exception.xml.responsetype=text/xmlfor OWS 1.1.0 version
External Entities Resolution¶
When processing XML documents from service requests (POST requests, and GET requests with FILTER and SLD_BODY parameters) XML entity resolution is used to obtain any referenced documents. This is most commonly seen when the XML request provides the location of an XSD schema location for validation).
GeoServer provides a number of facilities to control external entity resolution:
By default http and https entity resolution is unrestricted, with access to local file references prevented.
To restrict http and https entity resolution:
The built-in allow list includes w3c, ogc, and inspire schema locations:
In addition the proxy base url is included, if available from global settings.
Access to local file references remains restricted.
To allow additional external entity http and https locations use a comma or bar separated list:
To turn off all restrictions (allowing
filereferences) use the global setting Unrestricted XML External Entity Resolution.
This setting prevents
ENTITY_RESOLUTION_ALLOWLISTfrom being used.
