   * ``tcpListenQueueSize=SOMAXCONN``: int - Set the size of the listen queue. Default is ``SOMAXCONN``.
   * ``internalPipeBufferSize=0``: int - Set the size in bytes of the internal buffer of the pipes used internally to pass queries and responses between threads. Requires support for ``F_SETPIPE_SZ`` which is present in Linux since 2.6.35. The actual size might be rounded up to a multiple of a page size. 0 means that the OS default size is used. The default value is 0, except on Linux where it is 1048576 since 1.6.0.
   * ``exactPathMatching=true``: bool - Whether to do exact path matching of the query path against the paths configured in ``urls`` (true, the default since 1.5.0) or to accepts sub-paths (false, and was the default before 1.5.0).
-  * ``maxConcurrentTCPConnections=0``: int - Maximum number of concurrent incoming TCP connections. The default is 0 which means unlimited.  
+  * ``maxConcurrentTCPConnections=0``: int - Maximum number of concurrent incoming TCP connections. The default is 0 which means unlimited.
   * ``releaseBuffers=true``: bool - Whether OpenSSL should release its I/O buffers when a connection goes idle, saving roughly 35 kB of memory per connection.
   * ``enableRenegotiation=false``: bool - Whether secure TLS renegotiation should be enabled. Disabled by default since it increases the attack surface and is seldom used for DNS.
