Reduce WebSEAL's TTFB: how send the first fragment immediately

  • 1.  Reduce WebSEAL's TTFB: how send the first fragment immediately

    Hi community!

    A WebSEAL doesn't send the first fagment from the backend to the client, it collects the whole responce before sending it to the client side. i couldn't find documentation, that describes this behavior, but I could see it in the lab. I created a php script, that falls asleep for 5 seconds after sending first chunk. If I open the page direct from the web server, I can see the content of the first chunk and after 5 seconds I get the whole page. If I open the same page having WebSEAL between the browser and the web server I have to wait 5 seconds before I get something and then I get the whole page. I could see it also in the pdeweb.snoop log.
    Is there are a document that describes this behavior? Is it possible to make a WebSEAl to send the first chunk of the responce immediately after it was received from the backend?
