[squid-users] Intermittent access issue for ssl sites

Hi,

I have a Squid setup . Past 20 days am facing Intermittent access
issue while opening ssl based websites .

sitename: www.hdfcbank.com , and after than opening
'enetbanking.hdfcbank.com ' from the link provided in the Main Url .

Issue is that sometimes,unable to access enetbanking site. Received
following error in browser "connection to 203.199.21.80 failed " and
same time following log is observed in access.log file .
"1256646352.314 203 10.1.0.200 TCP_MISS/200 1115 CONNECT
enetbanking.hdfcbank.com:443 - DIRECT/203.199.21.80 -
1256646508.001 59474 10.160.11.69 TCP_MISS/503 0 CONNECT
enetbanking.hdfcbank.com:443 - DIRECT/203.199.21.80 -
1256646568.029 59973 10.160.11.69 TCP_MISS/503 0 CONNECT
enetbanking.hdfcbank.com:443 - DIRECT/203.199.21.80 -
1256646568.069 40 10.160.11.69 TCP_MISS/200 39 CONNECT
enetbanking.hdfcbank.com:443 - DIRECT/203.199.21.80 -

enetbanking.hdfcbank.com:443 - DIRECT/203.199.21.80 -"

Following are some observations:
1:Stopped content filtering websense and checked ,but still unable to
access website.
2:Squid Details. Version 2.5.STABLE14
3: Checked the squid faqs and disabled following options:
client_persistent_connections off
 server_persistent_connections off
4:Enabled negative_dns_ttl 1 second

Issue is for 1-2 min only. Please let me know is this related any
Squid configuration error or ISP dns issue .

Thanks in advance for help!!!!
