Hi Sandeep, Thanks for looking into it.
Yes, I tried that before, the value can be replaced correctly, but the webpage is just stuck there, no redirect happens. The result in html is <meta http-equiv="refresh" content="https://host:port/something";>, which however, should be <meta http-equiv="refresh" content="*1; url=* https://host:port/something";>. It seems the html meta refresh format requires *'1; url='*, where the 1 means stop for 1 seconds before refresh.
