This article is about how HTTP agents can be divided into several categories according to anonymity. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

1. Transparent proxy: use a transparent proxy to access the target server, and the other server knows to use the proxy and can identify the actual local ip address.

ADDR= proxy server IP.

HTTP_VIA= proxy server IP

HTTP_X_FORWARDED_FOR= your real IP.

The transparent proxy cannot hide the real ip address and therefore cannot break the target server limit.

2. Anonymous proxy: use an anonymous proxy to access the target server. The other party's server knows to use the proxy, but does not recognize the real IP.

ADDR= proxy server IP.

HTTP_VIA= proxy server IP.

HTTP_X_FORWARDED_FOR= proxy server IP

3. Highly anonymous agent.

Using a highly anonymous proxy server does not recognize not only your real ip, but also the proxy you use. The HTTP header information with which the high anonymous agent accesses the other server is as follows:

REMOTE_ADDR= proxy server IP

HTTP_VIA does not display

HTTP_X_FORWARDED_FOR does not display

The highly anonymous agent can well hide the local ip and visit the target website by disguising the ip, thus breaking the restriction of the ip of the website. Therefore, when choosing a proxy ip, be sure to choose an agent like Sun http, which has millions of dynamic highly anonymous ip every day. Only highly anonymous ip can break through various ip restrictions.

Http agent is an indispensable helper for network workers with high efficiency. In the most common cases, web crawlers often encounter the problem of restricting ip on the target site in the process of collecting data. This is an anti-crawler strategy, based on the frequency of ip visits.
