We chose to use an HTTP proxy to make it easier to change IP addresses over the network. Using HTTP proxy on the Internet can help promote marketing, data collection, so that users know HTTP proxy function; It can help to collect customer needs with crawlers, provide more powerful goods and services for customers and so on. Frequent actions in a short period of time, such as frequent scrolling or adding friends. This behavior severely damages the experience of other users, and many sites are sensitive to frequent operations, so use it appropriately. To remove this limitation, it is best to use proxy IP to perform the switching IP operation, so that we can work properly. The only way to be more secure is to use a high-hiding proxy IP address. Using a transparent proxy IP address exposes the real IP address of the client, and using a punic proxy IP address exposes the Internet using a proxy IP address.
Even if the proxy IP is used, we always leave some traces on the Internet, such as cookie information, account password information and so on. Before switching to the proxy IP, remember to clear these traces, and it is also best to clear them after the Internet. Each site has rules that limit the number of times a user can visit and the number of simultaneous online users under one IP address. If these rules are triggered, the site will be triggered to crawl back, this time to comply with the rules of the site, control the number of visits, etc.
If the agent high bandwidth, visit the web site of the speed, if the agent IP concurrency is too large, possible timeout or IP connectivity rate is low, so the success rate will drop, if concurrent low, possible business efficiency will decline, so the need to control each IP requests and concurrent, in order to better complete the business requirements.
