I’m a newbie to Nginx and I asked several time this problem to support and they were unable to find out a solution for this.

I have two problem with my this site.

1. I want to rid of from my the aforesaid errors. How can I solve this issue?

2. I want to open my site as “www.mysite.com”, now its opening as http://mysite.com instead of http://www.mysite.com. Domain AAA records are correct. I think there is a bad config in my ngnix.conf. Plz suggest me the correct configuration for this.

3. I think my Nginx.conf file is not optimized in a better way. I’m getting around 10k- 15k traffic each day. some time my site is opening very slowly. How can I speed up my site?

Thanks in Advance for your valuable suggestion.
