Script does not work on HTTPS

It seems that script does not send custom headers for HTTPS but it works for HTTP. For example, I tried below script

HTTPS

setHeader hdr1: 123
navigate https://google.com

Result : http://www.webpagetest.org/result/141111_S5_TGC/
Note that hdr1 was not sent to the server in above test.

HTTP

setHeader hdr1: 123
navigate https://google.com

Result : http://www.webpagetest.org/result/141111_0D_TKE/
Note that hdr1 was sent to the server in above test.

Any suggestion on how to send custom headers using script to HTTPS domains?

Thanks

There’s been a long-standing bug that I just haven’t fixed yet: https://github.com/WPO-Foundation/webpagetest/issues/67

Depending on the browser, it may work for IE or Firefox.
