%...f Filename
%...h Remote host
%...H The request protocol
%...{Foobar}i The contents of Foobar: header line(s) in the request sent to the server. Changes made by other modules (e.g. mod_headers) affect this.

%...q The query string (prepended with a ? if a query string exists, otherwise an empty string)
%...r First line of request
%...s Status. For requests that got internally redirected, this is the status of the *original* request --- %...>s for the last.
%...t Time the request was received (standard english format)
%...{format}t The time, in the form given by format, which should be in strftime(3) format. (potentially localized)

%...U The URL path requested, not including any query string.
%...v The canonical ServerName of the server serving the request.

(This directive was %...c in late versions of Apache 1.3, but this conflicted with the historical ssl %...{var}c syntax.)
%...I Bytes received, including request and headers, cannot be zero. You need to enable mod_logio to use this.
%...O Bytes sent, including headers, cannot be zero. You need to enable mod_logio to use this.
