    string map will replace all the string if it contains "/gamification", you need use regsub to replace first /gamification:

     

    11 % set uri "/gamification/gamification_uploads/header.jpg"

    /gamification/gamification_uploads/header.jpg

    (bin) 12 % string map -nocase {"/gamification" ""} $uri

    _uploads/header.jpg

    (bin) 13 % set uri

    /gamification/gamification_uploads/header.jpg

    (bin) 14 % regsub -nocase "/gamification" $uri "" new_uri

    1

    (bin) 15 % set new_uri

    /gamification_uploads/header.jpg

    You can simply tweak this part, so it matches your requirement.

    when HTTP_REQUEST {
if { [string tolower [HTTP::uri]] starts_with "/gamification" } {
HTTP::uri [string map -nocase {"/gamification/" "/"} [HTTP::uri]]
}
}

    Explanation:

    set newuri [string map -nocase {"/gamification" ""} $uri]

    Will give you "_uploads/header.jpg"

    But being specific like below,

    set newuri [string map -nocase {"/gamification/" "/"} $uri]

    Will give you "/gamification_uploads/header.jpg"

    Hope it explains.
