thanks for asking! I’m sandboxing on ubuntu feisty, nginx and mongrel… so the issue is only on personal localhost, productions servers work ok… application uses libevent, sesstrack and memcached and problems started when using xml for page caching… db is mysql. # Allow xml\_request to work with page caching map.connect ‘xml/ query/:controller/:action/:cat/:sub/:page’, :xml\_request =\> ‘1’ map.connect ‘xml/:controller/:action/:id’, :xml\_request =\> ‘1’ this error is driving me crazy… ---
