Host redirection not working for second host in iRule
Hi,
There is one issue i am facing in redirection - For eg below is the scenerio.
test.com -> https://test.com/redlab/login.html
lab.com -> https://lab.com/bluelab/login.html
We are using single Virtual Server & HTTP::host based irule for backend Pool connectivity.
Tried below irule for redirection - but redirection is working only for first host domain & is not working for second host domain ( for lab.com )
when HTTP_REQUEST {
if {[HTTP::host] equals "test.com" and [HTTP::uri] equals "/"} {
HTTP::redirect "https://test.com/redlab/login.htmll"
if {[HTTP::host] equals "lab.com" and [HTTP::uri] equals "/"} {
HTTP::redirect "https://lab.com/bluelab/login.html"}
}
}
Please let me know, if any modification to be done on abve irule for second host redirection also to work.
You may try Daniel_Wolf solution but your iRule has clear mistakes as the second "if" statement is in the first "if" statemet.
when HTTP_REQUEST {
if {[HTTP::host] equals "test.com" and [HTTP::uri] equals "/"} {
HTTP::redirect "https://test.com/redlab/login.htmll" }
if {[HTTP::host] equals "lab.com" and [HTTP::uri] equals "/"} {
HTTP::redirect "https://lab.com/bluelab/login.html"}
}or even better
when HTTP_REQUEST {
if {[HTTP::host] equals "test.com" and [HTTP::uri] equals "/"} {
HTTP::redirect "https://test.com/redlab/login.htmll"
}elseif {[HTTP::host] equals "lab.com" and [HTTP::uri] equals "/"} {
HTTP::redirect "https://lab.com/bluelab/login.html"}

Hi Preet_pk,
this iRule will satisfy your requirements:
when HTTP_REQUEST { if { [string tolower [HTTP::host][HTTP::path]] equals "domain-alpha.com.com/" } { HTTP::respond 301 -version 1.1 noserver Location "https://domain-alpha.com.com/redlab/login.html" } elseif { [string tolower [HTTP::host][HTTP::path]] equals "domain-beta.com.com/" } { HTTP::respond 301 -version 1.1 noserver Location "https://domain-beta.com.com/bluelab/login.html" } else { #default action } }
- The 301 response code indicates that the requested page has been permanently moved to the URL given in the Location header.
- -version 1.1 will set HTTP/1.1 (otherwise HTTP/1.0 would be used).
- noserver will prevent that the default server header (configured in HTTP profile, usually BigIP) is returned to the client.
I use HTTP::respond instead of HTTP::redirect, because:
HTTP::respond can use 301 / Moved Permanently
HTTP::redirect will alsways use 302 / Found or Temporary MovedHope this helps and happy F5 day
