How to enable WebSocket EdgeOne supports WebSocket protocol access, which enables the server to actively push data to the client. WebSocket protocol is a persistent protocol based on TCP, which implements full-duplex communication between the client and the server, allowing the server to actively send information to the client. How to get Client IP Geolocation Real client IP header allows you to create a custom origin-pull HTTP request header that carries the real client IP information. How to Custom Error Page EdgeOne provides support to redirect to a specified custom page and return a 302 status code when the origin server responds with specific error statuses. This helps your site inform users of the current website status by the customized error page, avoiding uncertainty regarding the specific cause and resolution when a request error occurs. How to Modifying HTTP Response Headers Support customization/adding/deleting HTTP node response headers (responding to the customer's direction), modifying HTTP node response headers will not affect the node cache. How to Modifying HTTP Request Headers When Edgeone nodes origin-pull, if the origin needs to obtain some specific information through the HTTP request header for business logic judgment or data analysis, such as: client device type, acceleration service provider. This can be achieved by customizing/adding/deleting HTTP origin-pull request headers (node origin-pull direction), where the header value supports variables, please refer to EdgeOne preset variables for details. How to Configuring Origin-Pull HTTPS You can specify the protocol that EdgeOne uses in the origin-pull request. How to Rewrite Host Header for Origin-Pull Host header rewriting enables you to rewrite the host header to the actual origin domain when the origin domain is different from the acceleration domain in the load balancing task.

How to use DNS Resolution This page mainly displays the number of resolution requests received by EdgeOne DNS. Only data from sites that support NS mode access is available. Cache How to improve the Cache Hit Rate of EdgeOne This article introduces how to reasonably use various configurations on EdgeOne, combined with your actual business scenarios for tuning, and improve the cache hit rate of files within the site. Custom Cache Key When you need to point the Request URL of the same path to different files based on request parameters, cookies, or HTTP request headers, or point the Request URL with different parameters to the same file, the custom Cache Key supports customizing the Cache Key identification of resources in the node, including concatenating query strings, concatenating HTTP headers or Cookie information, etc., so that the Request URL can correctly obtain the corresponding cached resources according to different scenarios. Cache Prefresh After the cache resources expire within the EdgeOne node, EdgeOne will follow the origin to obtain the latest resource files when receiving the corresponding client requests, which may cause a large increase in origin-pull requests during peak periods. The cache pre-refresh function can verify the validity of cache resources before they expire, without waiting for expiration, which helps maintain the real-time nature of resources and respond to requests more quickly. The cache pre-refresh time can be configured according to the percentage of the file cache TTL. Browser Cache TTL The Client browser cache TTL is the cache duration of resources in the browser, which by default follows the origin's Cache-Control headers. You can control the cache duration of resources in the browser by configuring EdgeOne's browser cache TTL without modifying the origin configuration. Cache Purge When your resource content is cached to the EdgeOne edge node, during the cache validity period, users accessing the resource will be directly responded by the EdgeOne edge node without triggering a return to the origin. URL Pre-Warming The cache pre-warming function allows resources to be cached on EdgeOne in advance. In this way, even if the client requests for the first time, it can be directly responded from the cache of EdgeOne without the need to follow the origin. How to use Cache Key Cache Key is used to determine whether the file resources accessed by users hit the edge caching content of EdgeOne, and it is the unique identifier of cached resources within the node.

Security How to use Exclusive DDoS Protection You can use this document to learn How to use Exclusive DDoS Protection. How to Configuration Region Blocking Rule If you find that all your attacks come from a specific region, or your business only allows access from specific regions and does not trust access from other regions, EdgeOne supports one-click blocking in the cleaning room by specifying a list of regions based on the source IP geographic region, helping you to custom block access requests from specified regions. After enabling region blocking, traffic from the blocked region to the EdgeOne site will be discarded. Supports multi-region and country traffic blocking. How to Configuration IP blocklist/allowlist EdgeOne DDoS protection service supports controlling client source IP blocking or releasing access requests by configuring IP blocklist and allowlist, thus limiting users accessing your application resources. How to use Exclusive DDoS Traffic Alarm The DDoS attack traffic alert function allows users to set custom attack traffic rate alert thresholds for DDoS protection instances. When the detected attack traffic rate exceeds the set threshold, the system will send an alert notification to help users understand and respond to potential DDoS attacks in a timely manner. How to Configuration Protocol Blocking Rule EdgeOne supports one-click blocking of source traffic to the site by protocol type. You can configure ICMP protocol blocking, TCP protocol blocking, UDP protocol blocking, and other protocol blocking. After the configuration is complete, when the attack traffic is detected with related Access request, it will be directly truncated.

How to use CC attack defense To avoid CC attacks, EdgeOne provides a pre-set CC attack protection strategy and enables it by default to ensure the stability of your site online. How to Custom rule in WAF Custom rules support matching client requests based on single rule matching conditions or multiple matching conditions. By allowing, intercepting, redirecting, and returning custom pages, you can control the request strategy of matched requests, which can help your site more flexibly limit the content that users can access. How to Configuration Rate Limiting in WAF In site operation, problems such as malicious resource occupation, business abuse, and brute force cracking often occur. If these problems are ignored, they will lead to a decline in service quality, generate high-cost bills, and may even cause sensitive data leakage. How to use Exception Rules in WAF Exception rules provide a centralized allowlist configuration option, allowing for quick configuration of valid requests to be released, avoiding interception by other modules. How to use Bot Many public or commercialized programs, including search engine crawlers, have fixed or default User-Agent header features and have specific purposes. Bot management policies include most public bot type features, and you can directly manage bot tools that meet these features. How to enable Active Detection in Bot In addition to analyzing the received client requests, identifying features in the headers and client IP, EdgeOne also provides an active detection bot identification method. Active detection can perform Cookie verification and session tracking on the client, as well as client behavior verification for interaction, and further identify whether the current visitor is a tool based on the client's interaction feedback. How to Custom Bot Rule When you need to customize fine-grained policies for specific bot behaviors or features based on existing Bot management policies, custom bot rules can provide you with flexible matching conditions (such as client IP, header information, request method, static feature recognition, and client reputation analysis results), and can be combined with disposal strategies that randomly select actions by weight, helping you create accurate management strategies to effectively manage the risks brought by bot access to the site. How enable Bot Intelligent analysis Bot Intelligent Analysis is suitable for situations where rapid deployment, identification, and analysis of website traffic patterns are needed. Bot Intelligent Analysis is based on a clustering analysis algorithm and a big data model intelligent engine, aiming to help you comprehensively judge the risk of requests from multiple perspectives and more conveniently use Bot management to quickly identify and deal with known or unknown bots, avoiding fixed single strategies being bypassed. How to use Origin Protection When Origin Protection is enabled, EdgeOne notifies you of the latest update of intermediate IPs of L4 proxy and site acceleration. You can sync them to the firewall rules of your origin, allowing only traffic from these IPs to your origin. Media Image Optimization Image processing is to resize and convert images. The process of processing, caching and responding is taken place on EdgeOne servers. Your own origin only needs to store the original images, thus reducing image management costs on your side. EdgeOne can also compress images to improve page load speed without sacrificing visual impact.
