If page-load-time is enabled in the AVR profile, and the response is small enough to not be chunked, AVR will "promise" to the client a CSPM injection in the response by adding to the Content-length header. If the response contains no <html> tag, AVR will "change its mind" and won't inject the JavaScript, causing the client to wait for the missing bytes until timeout.
Client waits many seconds until timeout.
Page-load-time is enabled in the AVR profile,
None
If page-load-time is enabled in the AVR profile, and the response is small enough to not be chunked, AVR will "promise" to the client a CSPM injection in the response by adding to the Content-length header. If no <html> tag is found in the response, the system now injects empty spaces to fill in the missing bytes in order to prevent the client from timing out.
