iRule to change URI Path

There are two problems with your rule. Look at the "first problem" comment which I have added below. This test will catch all requests with the eat9 domain. The subsequent eat9 tests will never execute.

Secondly, you have a misplaced closing bracket. See my "second problem" comment below. This bracket should be moved below the susequent pool statement. The effect of this is that every execution of the rule will attempt to evaluate $last_dir and $last_string, but neither of which have been defined as the definition is in the dead code after my first comment.

Thirdly, I would rewrite the whole thing with a switch statement instead of multiple elseif.

when HTTP_REQUEST { 
    if { [HTTP::host] eq "eat1.blueberry.cheesecakes.com" } { 
        pool PL_eat1.blueberry.cheesecakes.com_1443 
    } elseif { [HTTP::host] eq "eat2.blueberry.cheesecakes.com" } { 
        pool VSEMPINTWEB07_1444 
    } elseif { [HTTP::host] eq "eat3.blueberry.cheesecakes.com" } { 
        pool PL_eat3.blueberry.cheesecakes.com_1444 
    } elseif { [HTTP::host] eq "eat4.blueberry.cheesecakes.com" } { 
        pool PL_eat4.blueberry.cheesecakes.com_1444 
    } elseif { [HTTP::host] eq "eat5.blueberry.cheesecakes.com" } { 
        log local0.alert "hit for eat5.blueberry.cheesecakes.com -> PL_eat5.blueberry.cheesecakes.com_1444" 
        pool PL_eat5.blueberry.cheesecakes.com_1444 
    } elseif { [HTTP::host] eq "eat7.blueberry.cheesecakes.com" } { 
        pool PL_eat7.blueberry.cheesecakes.com_1444 
    } elseif { [HTTP::host] eq "eat8.blueberry.cheesecakes.com" } { 
        pool PL_eat8.blueberry.cheesecakes.com_1444 
    } elseif { [HTTP::host] eq "eat9.blueberry.cheesecakes.com" } {    first problem
        pool PL_eat9.blueberry.cheesecakes.com_1444 
    } elseif { ([HTTP::host] eq "eat9.raspberry.cheesecakes.com") && ([HTTP::uri] starts_with "/foneat") } { 
        pool PL_eat9.blueberry.cheesecakes.com_1444 
    } elseif { ([HTTP::host] eq "eat9.raspberry.cheesecakes.com") && ([HTTP::uri] starts_with "/css") } { 
        pool PL_eat9.blueberry.cheesecakes.com_1444 
    } elseif { ([HTTP::host] eq "eat9.raspberry.cheesecakes.com") && ([HTTP::uri] starts_with "/templates") } { 
        pool PL_eat9.blueberry.cheesecakes.com_1444 
    } elseif { ([HTTP::host] eq "eat9.raspberry.cheesecakes.com") && ([HTTP::uri] starts_with "/js") } { 
        pool PL_eat9.blueberry.cheesecakes.com_1444 
    } elseif { ([HTTP::host] eq "eat9.raspberry.cheesecakes.com") && ([HTTP::uri] starts_with "/images") } { 
        pool PL_eat9.blueberry.cheesecakes.com_1444 
    } elseif { ([HTTP::host] eq "eat9.raspberry.cheesecakes.com") && ([HTTP::uri] starts_with "/cache/*") } {

         Get the index of the last URI directory
        set depth [URI::path [HTTP::uri] depth]

         Parse the last directory in the path
        set last_dir [URI::path [HTTP::uri] $depth $depth]

         Parse everything after the last directory
        set last_string [string trimleft [string range string $last_dir end]]
    }    second problem 

    { HTTP::redirect "[HTTP::host]/$last_dir$last_string" } 
    { pool PL_eat9.blueberry.cheesecakes.com_1444 } 
}

Hi,

Thanks for the reply. Not sure how (first comment) eat9 test can catch all requests as is for the subdomain blueberry. subsequent test are for subdomain raspberry.

Thanks for the tip with switch I'll look into it.

PS. Yeah It could be an issue with my browser although I was able edit this question the edit window wasn't saving the double tilde I placed before and after the code, so I ended up having post another question.

Regards,

Hi,

I've worked how to strip the first two directories of the URI and parse the remaining subdirectories + basename + query string, which are then used to change the URI Path.

I've posted the info here -

Unfortunately couldn't get switch -glob to work but will keep trying. using elsif for now.

Thanks,

Dave
