Use VS Port difference Member port for https traffic

HI ngockq , 

First > there is a redirection returned to you from the origin server/pool member in response body , this is a know issue called Mixed Content , So I believe the best practices is to adjust this redirection from the server Code itself not to solve it by bigip , but as a last resort Bigip can solve it. 

> Take a Pcap from bigip and capture both client and server sides.
> Take HAR file from your browser : https://my.f5.com/manage/s/article/K10370211

> Download HAR file and open it in HAR file Analyser : https://toolbox.googleapps.com/apps/har_analyzer/
> identify your requests and server responses and look deeply on server responses body to see where is the mixed content happen , I mean kook at the response that you recieve prior to sending this request" https://IP_VS:9445/web/login.. and brower can not load page web. "

When you get it send the sample response body to the Server developer first to adjust it , if this not available you can use an iRule to replace " https://IP_VS:9445/ " by what you need to send in the following request , you can use string map function in the irule I think , please have a look to this Article to know how to construct the irule : https://community.f5.com/t5/technical-forum/irule-to-modify-http-response/td-p/134276

make sure to Sync the changes with the server developer.

I hope this insightful !
