What is a contract unit for Smart Content Delivery?
A.

www.ntt.com or global.ntt.net would require an additional contract.
Q.
Where are NTT Com's reverse proxy cache servers located?
A.
The reverse proxy cache servers are deployed in Tokyo, Osaka, and main data centers overseas such as San Jose, Chicago, Seattle, and London, etc. We will expand sites to meet customers' demands.
Q.
Do we need web servers to use Smart Content Delivery?
A.
At least minimal equipment and network such as a web server/streaming server and Internet connectivity are necessary. NTT Communications also offer hosting services and Internet connectivity.
Please contact our sales personnel or sales engineer for details.
Q.
Is Smart Content Delivery beneficial for frequently refreshed content?
A.
Yes, it is. In the case of heavy end user access, Smart Content Delivery efficiently caches and delivers frequently refreshed content such as news content. Therefore, the content will be displayed quickly and the origin servers will be offloaded.
Q.
Do my origin servers have to be in the NTT Communications data center to use Smart Content Delivery?
A.
No, if your web server is on the Internet, you can introduce Smart Content Delivery no matter which ISP you use. You can easily apply Smart Content Delivery to your web site by changing the DNS configuration.
Please contact our sales personnel for details.
Q.
Is expired content left in cache servers and delivered to end users?
A.
You can flexibly manage cache control header configurations per object, directory and page, so that you can control the expiration time of the content by yourself. We offer a cache content eject function. To expire your content, you can eject and refresh the old content.
Q.
How are we charged?
A.
Charges consist of a combination of fixed basic charges and variable charges. The variable charges are proportional to the amount of total content transmissions (in Gigabytes) from the cache server.
Please contact our sales personnel or sales engineer for details.
Q.
What is a reverse proxy cache?
A.
A reverse proxy cache server is a server which copies, accumulates and distributes the web content of the customer in place of the origin servers. The reverse proxy cache servers are deployed on the Internet such as on the NTT Communications Global IP Network.
