ip name-server x.x.x.x
SW# telnet www.btc.com.sa 80
Translating "www.btc.com.sa"
% Bad IP address or host name
Although i have ping in the DNS IP .. I need to using my DNS server where ( x.x.x.x) is my DNS server IP
So any advice ... Thanks in advance

Perhaps you have DNS lookups turned off. Try adding:
ip domain-lookup

Now Every thing working fine .. but when i using the name-server 8.8.8.8 although i created
ip name-server x.x.x.x
So

It working fine
but when i using my DNS server ip
http get http://www.btc.com.sa/flash/AC_RunActiveContent.js name-server x.x.x.x

Latest operation return code: DNS query error

At a guess; you have an access-list or firewall configured blocking the DNS queries.

It could be on the DNS server, the router itself, or some device between the router and the DNS server.

But the DNS IP is pingable from my router .. but no trace route on it

Well, I will check this issue .. Last thing plz what about the HTTPS , As you know most of pages in right now HTTPS .. I think the IP SLA for HTTP not support HTTPS such as facebook page .. So any advice about this issue .. Thanks
