I don't know whats going wrong with my Magento 1.9 setup. From last few days I have seen my /var/session directory remains same with no files generated. It's showing empty content.
Configuration -> Web -> Session Cookie Management Has below data
Cookie Lifetime : 3600
Cookie Path :
Cookie Domain : .domain.com
Use HTTP Only : Yes
Cookie Restriction Mode : No
Please suggest how to resolve this issue or this is not a problem. It's working fine.
