Yes, of course http get is a better option for web servers.
Strangely the ifportup line doesn't seems to work on my server. I get
"Host ... not found: 2(SERVFAIL)"
Could this be the caused by my server version, 4.4.1 ?

You can do with ifportup also like this:
www.domain.com 60 IN LUA A "ifportup(443,
{{'192.168.1.10'},{'192.168.2.20'}}, {timeout=5})"
I suggested ifurlup because it will actually do http get request and
verify if it responds with 200 OK message. A better health check for
web servers.

Thank you !
I wasted 4 hours looking for a valid combination :(
Is this not possible with ifportup ?

Hi,
If its a web server I would suggest using url check instead of port
check like below:
www.domain.com 60 IN LUA A
"ifurlup('https://www.domain.com',
{{'192.168.1.10'},{'192.168.2.20'}}, {timeout=5})"

Hi,
I'm attempting to implement a simple fail-over mechanism between
two web servers but I'm not able to find the right syntax.
www LUA A (";if ifportup(443, {'192.168.0.10'}) then "
" return '192.168.0.10'
"
"else "
" return '10.0.0.10'
"
"end ")
Any suggestions are welcome !
