A POP is a Point Of Presence, an access point to the Internet. It is a physical, strategically placed location that houses multiple CDN servers.
Note: custom price plans are very common in the CDN market, especially for large volume customers. We recommend you always talk to the CDN provider about your needs and requirements and work with them to get a best-fit deal.
Features & Support
ChinaCache supports 'soft TTL' or 'soft invalidation'. This means that the customer can configure after how long the CDN needs to check on the origin if a file is still valid.
Push (upload to CDN servers)
Purge time is 3 to 5 minutes. No more than 100 purge requests at one time.
Contendo support various types of flush expressions such as /* ; /subfolder/* ; /subfolder/*.jpg; etc.
Resend from origin, or compress on edge
GZIP is not on by default, so make sure you don't forget to turn it on. Resend from origin, or compress on edge
Cotendo also offers the possibility to deactivate Gzip on the origin and have Cotendo do the Gzipping on their servers (compression-on-the-fly), for an even faster delivery to end users and less load on the origin. And, Cotendo supports exclude lists. If a specific user-agent requests a compressed object, the Cotendo server can decide to send it uncompressed due to known compliancy issues that the user-agent might have.
Honors all origin server headers
Cotendo will comply to the following cache headers: Pragma: no-cache, Expires: valid date, Cache-Control: no-cache or no-store or max-age=x.
Can override origin server headers
Cotendo supports full modifications of any headers. The customer can add his own headers, set the value of any existing header and even re-name some headers while preserving their value.
