The current consensus suggests that mitigating RC4 vulnerabilities is
more important than BEAST attack concerns, which are all but mitigated
client-side. If you want to deploy protocols to cater for a wide range
of browsers (including XP IE) implement the following (that will
fall-back to RC4 as a last resort):

ssl_ciphers EECDH+ECDSA+AESGCM EECDH+aRSA+AESGCM EECDH+ECDSA+SHA384
EECDH+ECDSA+SHA256 EECDH+aRSA+SHA384 EECDH+aRSA+SHA256 EECDH+aRSA+RC4
EECDH EDH+aRSA RC4 !aNULL !eNULL !LOW !3DES !MD5 !EXP !PSK !SRP !DSS
+RC4 RC4

Otherwise, exclude RC4 with the following:

ssl_ciphers EECDH+ECDSA+AESGCM EECDH+aRSA+AESGCM EECDH+ECDSA+SHA384
EECDH+ECDSA+SHA256 EECDH+aRSA+SHA384 EECDH+aRSA+SHA256 EECDH+aRSA+RC4
EECDH EDH+aRSA RC4 !aNULL !eNULL !LOW !3DES !MD5 !EXP !PSK !SRP !DSS !RC4
