dav_ext_methods
The `dav_ext_methods` directive enables additional WebDAV methods in NGINX configurations.
Description
The dav_ext_methods directive is part of the NGINX WebDAV extension module that enhances the basic functionality provided by the standard NGINX WebDAV module. With this directive, administrators can specify which additional WebDAV methods (PROPFIND, OPTIONS, LOCK, UNLOCK) should be enabled in the specified context (http, server, or location). By default, NGINX does not support these methods in the base WebDAV implementation, so this directive is essential for implementing complete WebDAV functionality.
When used, each method can be listed as an argument, allowing for fine-grained control over which methods are activated. This allows NGINX to handle requests for retrieving properties (PROPFIND), checking supported methods (OPTIONS), and working with resource locks (LOCK and UNLOCK). It is crucial that the corresponding locking functionality is enabled through the dav_ext_lock and dav_ext_lock_zone directives to ensure complete lock support when LOCK and UNLOCK methods are included.
Incorrect configuration or failure to enable required directives can lead to limited WebDAV functionality, which may affect applications relying on WebDAV for document management or collaborative editing. Therefore, when enabling these methods, ensure that all related configurations are properly set up to achieve the desired outcome.
Config Example
server {
location /webdav {
dav_methods PROPFIND OPTIONS LOCK UNLOCK;
dav_ext_lock_zone zone=webdav_locks:1m timeout=1m;
dav_ext_lock zone=webdav_locks;
# other configurations
}
}Ensure that the required methods are supported by the server and correctly configured.
Neglecting to define a lock zone when using LOCK/UNLOCK methods can lead to errors.
Using a high lock timeout may cause performance degradation if many locks are retained.
