VuGen 11.5x and 12.x are unable to record an https page with Chrome browser.
In the recording log the following error message can be found:
Analyze segments filter initialization ******
****** Error: found multiple wplus_http_wsock_request_ex events with the same processID, sessionid and httpid!
It is followed by "Alternate-Protocol: 443:quic" as shown in the sample below:
****** Response Header For Transaction With Id 316 ******
HTTP/1.1 304 Not Modified
X-Xss-Protection: 1; mode=block
Date: Thu, 10 Jul 2014 14:15:39 GMT
The error message is caused by QUIC because LoadRunner currently does not support it.
Once Chrome browser sees Alternate-Protocol: 443:quic header, it switches to QUIC. This is the reason why Chrome cannot be used.
To overcome the problem during recording with VuGen use a browser which does not support QUIC such as Internet Explorer or Firefox.
