https redirection

Hi Anush,

accuracy and performance wise the code below would be most effective...

if { ( [HTTP::host] eq "devcentral.com" ) and ( [HTTP::path] starts_with "/groups/Research/" ) } then {
    HTTP::redirect "https://f5.com/devresearch/[string range [HTTP::uri] 17 end]"
}

... almost equals (but without -NOCASE support)...

if { ( [HTTP::host] eq "devcentral.com" ) and ( [HTTP::path] starts_with "/groups/Research/" ) } then {
    HTTP::redirect "https://f5.com/devresearch/[findstr [HTTP::uri] "/groups/Research/" 17 end]"
}

... closely followed by a ...

if { ( [HTTP::host] eq "devcentral.com" ) and ( [HTTP::path] starts_with "/groups/Research/" ) } then {
    HTTP::redirect "https://f5.com/devresearch/[string range [HTTP::uri] [string length "/groups/Research/"] end]"
}

if { ( [HTTP::host] eq "devcentral.com" ) and ( [HTTP::path] starts_with "/groups/Research/" ) } then {
    HTTP::redirect  "https://f5.com/devresearch/[findstr [HTTP::uri] "/groups/Research/" [string length "/groups/Research/"] end]"
}

if { ( [HTTP::host] eq "devcentral.com" ) and ( [HTTP::path] starts_with "/groups/Research/" ) } then {
    HTTP::redirect "https://f5.com/devresearch/[getfield [HTTP::uri] "/groups/Research/" 2]"
}

... followed by the less accurate (the [string map] search patter may occour multiple times) and less performant method ...

if { ( [HTTP::host] eq "devcentral.com" ) and ( [HTTP::path] starts_with "/groups/Research/" ) } then {
    HTTP::redirect "https://f5.com[string map [list "/groups/Research/" "/devresearch/"] [HTTP::uri]]"
}

Update: Included the [findstr] command.
