-
-Partial depth detection is a feature that enables Snort to more
-quickly detect and block malicious requests. It is configured by the
-partial_depth_body parameter which can take values in the range
--1-16384 bytes. The feature is enabled by setting partial_depth_body
-to some non zero value. When the feature is enabled and either, the
-number of bytes received in the request body is below the value
-specified by partial_depth_body, or partial_depth_body is set to -1,
-unlimited; it immediately forwards the available part of the message

-consumes somewhat more of the sensor’s resources.
+5.10.3.4. partial_depth_body and partial_depth_header
+
+Partial depth detection enables faster threat detection by
+immediately forwarding partial message data to the detection engine
+before the complete message arrives. This feature can be configured
+independently for HTTP request bodies (partial_depth_body) and
+headers (partial_depth_header).
+
+Configuration options:
+0 (default):    Feature disabled
+-1 (unlimited): Enable for all partial messages regardless of size
+Positive value: Enable only when received bytes are below the specified threshold
+
+For HTTP request bodies only, the maximum configurable value is
+16,384 bytes. Use partial_depth_body = -1 when early detection is
+needed beyond this limit. HTTP headers have no such limitation.
 
 This feature is turned off by default by setting partial_depth_body =
-0. To activate it, set partial_depth_body to the desired value.
