Host re-direct except for directory?

Try this:

when HTTP_REQUEST {
     Check if domain is "www.domain.com"
    if {[string tolower [HTTP::host]] eq "www.oil.com"}{
         Check if URI isn't /specialdirectory
        switch -glob [string tolower [HTTP::uri]] {
           "/ger" -
           "/ger/" -
           "/ger/*" {
                 Exit this event from this iRule
                return
           }
           default {
                 Redirect everything else to the following
                HTTP::redirect "http://www.test.com/abc"
           }
        }
    }
}

Update: Whoops. Shouldn't try typing fast before I've had my coffee. Missed a closed bracket and quotes.

Thanks Joel am getting the following error

 

 

line 3: [parse error: PARSE syntax 107 {syntax error in expression "[string tolower [HTTP::host]] eq www.oil.com": variable references require preceding $}] [{[string tolower [HTTP::host]] eq www.oil.com}]

Put www.oil.com in quotes. And you don't need the string tolower on HTTP::host.

I've updated the rule above.

 

 

@Jason: Most browsers will convert the Host: header to lowercase if the user specifies it in mixed or uppercase in the Address bar -- but not all do. And if you look at RFC-2396 (URI specifications), it's totally silent on case conversion in the authority section of a URI (section 3.2) but explicitly states it in the scheme section (section 3.2)... and then goes on in section 6 (URI normalization) to describe an authority "host" as merely "equivalent" when mixed case but does not _require_ it to be normalized.

 

 

Which is why I've found plenty of tools that will happily set a Host header with mixed case! Some web-crawlers, for example. Dang "standards"...

I think you've still got an extra ] here:

    if {[string tolower [HTTP::host]] eq "www.oil.com"]}{

Many thanks Joel I've just tested the irule and it works perfectly thanks again for your help.
