gps.conf - SUPL_TLS_HOST and SUPL_TLS_CERT variables

[bovirus]

I found in many sites the same optimized file (gps.conf) in thsi case for Italy

NTP_SERVER=it.pool.ntp.org
NTP_SERVER=0.it.pool.ntp.org
NTP_SERVER=1.it.pool.ntp.org
NTP_SERVER=2.it.pool.ntp.org
NTP_SERVER=3.it.pool.ntp.org
DEBUG_LEVEL =0
INTERMEDIATE_POS=0
ACCURACY_THRES=0
REPORT_POSITION_USE_SUPL_REFLOC=1
ENABLE_WIPER=1
XTRA_SERVER_1=http://xtra1.gpsonextra.net/xtra.bin
XTRA_SERVER_2=http://xtra2.gpsonextra.net/xtra.bin
XTRA_SERVER_3=http://xtra3.gpsonextra.net/xtra.bin
XTRA_SERVER_4=
XTRA_SERVER_5=
SUPL_NO_SECURE_PORT=3425
SUPL_PORT=7276
SUPL_HOST=supl.google.com
SUPL_SECURE_PORT=7275
C2K_HOST=c2k.pde.com
C2K_PORT=1234
DEFAULT_AGPS_ENABLE=TRUE
DEFAULT_SSL_ENABLE=FALSE
DEFAULT_USER_PLANE=TRUE
SUPL_TLS_HOST=FQDN
SUPL_TLS_CERT=/etc/SuplRootCert

As I explianed a previous request I found several NTP servers (with same string variable name - strange)

At the end of configuration file I found two variables that I didn't fin in the Faster GPS
app

SUPL_TLS_HOST=FQDN
SUPL_TLS_CERT=/etc/SuplRootCert

Which are the meaning of theese variables and why didn't are availble in Faster GPS?
