+#      in play, the proper HTTP/2 stream reset did not trigger with H2_ERR_HTTP_1_1_REQUIRED.
+#      Fixed. [Michael Kaufmann]

+#+    <p>By default, the server merges (or collapses) multiple consecutive slash
+#+    ('/') characters in the path component of the request URL.</p>
+#+
+#+    <p>When mapping URL's to the filesystem, these multiple slashes are not 
+#+    significant.  However, URL's handled other ways, such as by CGI or proxy,
+#+    might prefer to retain the significance of multiple consecutive slashes. 
+#+    In these cases <directive>MergeSlashes</directive> can be set to 
+#+    <em>OFF</em> to retain the multiple consecutive slashes.  In these
+#+    configurations, regular expressions used in the configuration file that match
+#+    the path component of the URL (<directive>LocationMatch</directive>,
+#+    <directive>RewriteRule</directive>, ...) need to take into account multiple 
+#+    consecutive slashes.</p>
