Redirection should be on F5 side for client requests with Upper case URI to Lower case URI.

e.g.

// config

[root@ve13a:Active:In Sync] config  tmsh list ltm virtual bar
ltm virtual bar {
    destination 172.28.24.10:80
    ip-protocol tcp
    mask 255.255.255.255
    pool foo
    profiles {
        http { }
        tcp { }
    }
    rules {
        qux
    }
    source 0.0.0.0/0
    source-address-translation {
        type automap
    }
    translate-address enabled
    translate-port enabled
    vs-index 3
}
[root@ve13a:Active:In Sync] config  tmsh list ltm rule qux
ltm rule qux {
when HTTP_REQUEST {
  if { [HTTP::uri] ne [string tolower [HTTP::uri]] } {
    HTTP::respond 301 noserver Location http://[HTTP::host][string tolower [HTTP::uri]]
  }
}
}

// test

[root@ve13a:Active:In Sync] config  curl -I http://172.28.24.10/fR/PAges/DEfauLT.aspx

you may have to perform further troubleshooting such as tcpdump/ssldump, http analyzer tool or irule logging to see where the problem is.
