Not receiving X_REQUESTED_WITH request header in Apache localhost

由 假如想象 提交于 2019-12-13 05:24:24

Though the header is getting set, Apache seems to be dropping it before my .php script runs. I can see the request header in Chrome, but it's

This question was more about the specific UI task whether or not the

Simulate latency between packets for HTTP POST requests with Fiddler

由 断了今生、忘了曾经 提交于 2019-12-13 04:17:00
问题 I can see how I can script an overall latency in Fiddler using the ScriptEditor, using something like this: if (oSession.HostnameIs("www.testsite.co.uk")) { oSession["request-trickle-delay"] = "500"; } However, I need to be more specific and specify a delay between the first packet of the request which contains the header, and the secondary packets that contain the body .
