redirection loop

Question

Hi all,&nbsp;
&nbsp;Anybody could help me on this scenario&nbsp;
&nbsp;A customer wants to redirect their website with 301 response with the following scenarios.&nbsp;
&nbsp;1) customer.co.nz -&gt; http://www.customer.co.nz/Pages/default.aspx&nbsp;
&nbsp;2) www.customer.co.nz -&gt; http://www.customer.co.nz/Pages/default.aspx&nbsp;&nbsp;
&nbsp;I was able to sort the first one with this irule:&nbsp;&nbsp;
&nbsp;when HTTP_REQUEST {
&nbsp;   if { [string tolower [HTTP::]] equals "customer.co.nz" } {
&nbsp;      HTTP::respond 301 location http://www.customer.co.nz/Pages/Default.aspx
&nbsp;     }
&nbsp;}&nbsp;&nbsp;
&nbsp;But on the second one when I apply the rule below it says on my browser "redirection loop"&nbsp;&nbsp;
&nbsp;when HTTP_REQUEST {
&nbsp;   if { [string tolower [HTTP::]] equals "www.customer.co.nz" } {
&nbsp;      HTTP::respond 301 location http://www.customer.co.nz/Pages/default.aspx"
&nbsp;   }
&nbsp;}&nbsp;&nbsp;
&nbsp;I'm not sure what's wrong with the second rule, they are separate irule and both mounted on one virtual server.&nbsp;
&nbsp;Thanks.

Hi, &nbsp;
&nbsp; Try This iRule, it should works with both scenarios. &nbsp;
&nbsp; when HTTP_REQUEST 
&nbsp; if {([string tolower [HTTP::host]] contains "customer.co.nz") and ([HTTP::path] equals "/")} { 
&nbsp;    HTTP::respond 301 location http://www.customer.co.nz/Pages/default.aspx 
&nbsp; } &nbsp;
&nbsp; or instead of HTTP::respond 301 .... you can type HTTP::redirect "http://www.customer.co.nz/Pages/default.aspx" but this redirection will be 302 response instead.  &nbsp;
&nbsp; HTH &nbsp;

Hi Abdul, 
&nbsp;  
&nbsp; The rule doesn't work it's giving me the error below: 
&nbsp;  
&nbsp;  
&nbsp; 01070151:3: Rule [Trial_irule] error: line 1: [wrong  args] [when HTTP_REQUEST ] line 2: [command is not valid in the current scope] [if {([string tolower [HTTP::host]] contains "customer.co.nz") and ([HTTP::path] equals "/")} { HTTP::respond 301 location http://www.customer.co.nz/Pages/default.aspx }]

Hi F5_user, 
&nbsp;  
&nbsp; Sorry for that, just add one open bracket { after HTTP_REQUEST, and a close bracket } at the end of the iRule.  &nbsp;

Hi Abdul,&nbsp;
I tried same, but still getting into redirect loop.
when HTTP_REQUEST {
if {([string tolower [HTTP::host]] contains "www.test.com") and ([HTTP::path] equals "/")} { 
HTTP::respond 301 location "http://www.test.com/en-us"
} 
}&nbsp;

Hi avi123,
in http://www.test.com/en-us path is /
en-us is a fragment identifier and is not part of path
are you sure the fragment is sent to the F5? look this thread for more info.
