I send few ajax requests to my site. First running creating document, others check him status. But symfony not respond while first process is working. All processes wait in queue while end first. If look in log i see:
request.INFO: Matched route "start creating". work first request.INFO: Matched route "check" work first request.INFO: Matched route "check" work first .... event.DEBUG: Notified event "kernel.response" to listener for first process event.DEBUG: Notified event "kernel.response" to listener for second process etc
Why symfony very strange processes requests?
