Editor to share with you how to solve the problems often encountered by the reptile agent IP, I believe that most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

Crawler IP agents often encounter some strange problems in their use, the most common of which may be timeouts and slow access. How to test and solve.

1. One's own network environment is unstable and requires timeout.

Test methods and solutions: if conditions permit, you can use the server for testing. Home networking can try to replace the network test. If the network is used normally after changing the network, explain the reason for the network. It is recommended to use it after changing or upgrading the network configuration.

2. The content returned by the visited target server is large, and the response of the web page is slow.

Test method and solution: delete the agent, directly visit the local target website for testing, adjust the browser to developer mode, observe the file information and size of the network request, and record the time when the request was loaded successfully. the response of the target server becomes slower as the effect of the proxy request is the same. In this case, the agent and the customer themselves cannot be optimized.

3. The proxy server network is unstable.

Test method and solution: change the proxy IP to test, the general proxy server network is unstable.

4. The proxy request sent when using the proxy IP is too high, the pressure of the proxy server is too high, and the performance of the proxy server becomes the bottleneck.

Test methods and solutions: you can stop all proxy requests and then test them on the browser using the browser plug-in. If normal, it may be caused by too many concurrent proxy requests.
