PHP asks for the following ISAPI variables, in this order:

HTTP_COOKIE *
ALL_HTTP *
APPL_MD_PATH
APPL_PHYSICAL_PATH
AUTH_PASSWORD
AUTH_TYPE
AUTH_USER
CERT_COOKIE +
CERT_FLAGS +
CERT_ISSUER +
CERT_KEYSIZE +
CERT_SECRETKEYSIZE +
CERT_SERIALNUMBER +
CERT_SERVER_ISSUER +
CERT_SERVER_SUBJECT +
CERT_SUBJECT +
CONTENT_LENGTH
CONTENT_TYPE
LOGON_USER
HTTP_COOKIE *
HTTPS
HTTPS_KEYSIZE +
HTTPS_SECRETKEYSIZE +
HTTPS_SERVER_ISSUER +
HTTPS_SERVER_SUBJECT +
INSTANCE_ID
INSTANCE_META_PATH
PATH_INFO
PATH_TRANSLATED
QUERY_STRING
REMOTE_ADDR
REMOTE_HOST
REMOTE_USER
REQUEST_METHOD
REQUEST_URI
SCRIPT_NAME *
SERVER_NAME
SERVER_PORT
SERVER_PORT_SECURE +
SERVER_PROTOCOL
SERVER_SOFTWARE
URL
SCRIPT_NAME *
ALL_HTTP *


The ones marked with a * are requested twice, and the ones marked with a + shouldn't be requested unless HTTPS is set to 'on'. In all, 17 out of the 44 calls to GetServerVariable are avoidable.

Went to fix this in CVS and it seems Zeev (or someone) has already done this.
