Response body is logged in category LWP_Response_Body.* so it can be separated. For example, to dump response body dumps to directory instead of file: use Log::ger::Output Composite => ( category_level => {LWP_Response_Body => 'off'}, outputs => { Dir => { conf => { path => "/path/to/dir" }, level => 'off', category_level => {LWP_Response_Body => 'trace'}, }, } ); FAQ Why not subclass? By patching, you do not need to replace all the client code which uses LWP (or WWW::Mechanize, etc). SEE ALSO Use Net::HTTP::Methods::Patch::LogRequest to log raw HTTP requests being sent to servers.
