Basic features

Client Console

• Self-service Configuration: The  product supports self-service configuration deployment. Users can manage the  configuration acceleration content and certificates. 

• Statistical Analysis:  The product supports display of bandwidth, traffic, number of requests, QPS,  hit ratio, status code and PV/UV, as well as traffic and number of requests by region and carriers, so that customers can know their service information.

• Refresh and Prefetch: Refresh and  prefetch operations.

• Log Download: The product supports log download.

• Billing Details: The product supports  changing the billing mode and querying usage of resource packages.

Intelligent DNS Resolution

• According to the geographical location of the user, the product collects the operating status of node equipment and selects the optimal node to provide services through logical operation.

Intelligent Cache

• Custom cache: The product supports caching according to the cache header time of the origin and customizes caching rules based on the file type and directory to meet diversified  caching requirements of customers.

• Multi-level caching: Edge and parent layer multi-level caching. When the edge does not hit the cache, the edge requests the parent layer for cache resources, which increases the cache hit ratio.

• Cache sharing: Different domain names with the same content share the cache to reduce retrieval and increase the hit ratio.

• Segment-based caching: Large files can be cached by segment to reduce the sudden increase of back-to-origin bandwidth caused by complete file pull.

• Filtering of parameters after question mark: Question mark ignorance setting: For content of the same file,  different parameters after the question mark can be ignored when the file is  cached.

• Error page caching: The product supports caching error pages to reduce the retrieval pressure.

Dynamic acceleration

• Real-time detection: Nodes perform detection in real time to obtain the current network conditions and report the information to the central server as the basis of intelligent routing.

• Intelligent routing: The Results detected by accelerated nodes in real time is used and the optimal link algorithm self-developed by eSurfing Cloud is combined to obtain the optimal transmission path and guarantee the effect of dynamic content retrieval.

Transmission Optimization

• Link optimization: The product supports long connection holding and link reuse to save the three-way handshake time and improve the access effect.

• Content optimization: The intelligent compression technology is used to optimize transmitted content and improve the transmission efficiency.

Upload acceleration

• The product supports acceleration of POST and PUT requests.

Retrieval mode

• The product supports retrieval based on domain name and retrieval based on IP address.

• The product supports retrieval load balancing policies such as active/standby, weighted polling and preference by region, operator and IP address.

• The product supports changing the retrieval host.

Retrieval Bandwidth Optimization

• The product supports sharing of multiple domain name files to reduce the retrieval of same files and sets up intermediate nodes between the source and the edge to reduce the retrieval bandwidth.

Supported IP Protocols

• The product supports both IPv4 and IPv6.

Restriction on Total Bandwidth

• The product supports restricting the total bandwidth of the customer and controls the bandwidth cost within the budget.

Error Page Redirection

• When the source site returns an abnormal response, the node returns it to the specified page.

Header Customization

• The product supports adding and deleting a request header or response header.
  

Protocol Support

• The product supports HTTP and HTTPS acceleration.

• The product supports websocket acceleration.

• The product supports HTTP2.0.

Offline Mode

• When the source site fails, the content cached by nodes is used and files are not retrieved or verified to determine whether they expire.
  

The product supports out-of-order requests.

• The product supports out-of-order range requests.
  

Content Update in Seconds

• Through the unique shark technology of eSurfing Cloud, the delay of file push update is reduced from two to five minutes to seconds, avoiding the problem of late update, which is particularly important for e-commerce, information and video customers.
  

Content Preloading

• The product supports preloading content files to service nodes to avoid source site congestion caused by concurrent retrieval when content is published externally and improve user experience.
  

Data Compression

• Some text content can be actively compressed, mainly including html, js and css files.
  

Source Site Monitoring

• The product provides the source site monitoring service. When the source site breaks down and cannot provide services, the system switches services to the standby source site.
  

Value-added Services

Anti-theft chain

• The product supports Refer anti-leech, UA blacklist and whitelist and IP address blacklist and whitelist to reduce the number of requests from illegal sources, avoid unnecessary bandwidth and traffic costs   and protect content copyrights.
  

Log Service

• By default, the product provides an API and log download on the customer console.
  

Special Ports

• The product supports access to special ports.
  

IPv6 Upgrade

• Without any transformation of the customer's origin, IPv6 access can be upgraded with one click to meet the policy requirements of the national IPv6 scale deployment campaign.
