HAProxy how to detect url is IP address instead of domain name

I want to redirect to http://domainname if user types http://ip address. What would be the frontend rule?

For example, this rule can find out if www is prefixed to a domain and if not redirect to www.domain.com.

http-request redirect code 301 location      \
  http://www.%[hdr(host)]%[capture.req.uri]  \
  unless { hdr_beg(host) -i www }

Similarly, I want to redirect to www.domain.com when user types IP address in browser.

Solution

  • Since user types IP address in browser, this may work:

     http-request redirect code 301 location http://www.example.com%[capture.req.uri] if { hdr_reg(host) -i 127.0.0.1|192.168.1.100 }`

    but it fails if user specifies Host: example.com
