allow one url from blocks geolocation

It seems your first if statement is wrong, because it lowers all strings in [HTTP::uri] and then it is compared to a string which includes uppercase characters. So there will never be a match. Second, the '[whereis ip country]" command returns a string containing the two-letter country code. So it will not match 'Sweden'.  And the ASM::unblock command can't be used in the HTTP_REQUEST event.

See:

• whereis (f5.com)
• ASM::unblock (f5.com)

So, your iRule should be more like:

when ASM_REQUEST_DONE {
    if { ([string tolower [HTTP::uri]] eq [string tolower "/Arabic/MediaCenter/News/Pages/Infectious-Disease-Week.aspx"]) and ([whereis [IP::client_addr] country] ne "SE") } {
        ASM::unblock
        log local0. "[ASM::violation_data]. Unblocked for [IP::client_addr]"
    } else {
        return
    }
}
