CURL and proxy collaboration features: from features to step-by-step configuration
cURL – a common cross-platform command-line utility that provides efficient interaction with a huge number of different servers using all kinds of protocols that have the URL syntax. It automates the transfer of files, builds a sequence of such operations. The maximum effectiveness of using this program when scraping on the network, the stability and security of the process is ensured by the joint work of cURL and a proxy server. Their interaction will be especially effective in the case of multi-threaded grabbers, as well as in debugging issues.
Let's take a closer look at benefits of using cURL through mobile proxies, basic setup points, nuances of choosing a proxy for work with cURL.
Benefits of working with cURL through mobile proxies
Thanks to the proxy server, all requests that will come from your computer will be anonymous. No one will calculate your real IP address, because when passing through the intermediary server, it will be substituted. As a result – absolutely anonymous connection, the absence of the possibility of blocking by sites, search engines, a high level of security of interaction on the Internet. That is, when interacting with a remote server via cURL, you get a reliable technical intermediary.
Such a solution would be optimal for people whose professional activities are related to parsing large amounts of data. None of the existing systems today will allow you to launch a huge number of requests per minute from one IP address. Literally immediately after such actions, protection against DoS attacks will automatically turn on at the server level, because this is how your actions will be regarded. As a result – instant lock. And the only way to solve such a problem – use with cURL proxy.
Peculiarities of connecting mobile proxies to cURL
The process of connecting mobile proxies to the cURL program is quite simple and will only take a few minutes. It is necessary to perform a series of actions in the following sequence:
- Opening a personal code in a cross-platform cURL utility.
- Find in the code a line called "CURLOPT_PROXY". Next to this inscription, enter the IP address and port of the proxy (it will be available to you in your account after purchasing a proxy), separating them with a colon.
- On the line below, next to "CURLOPT_PROXYTYPE"; you need to specify the type of proxy server that you plan to use in your work: HTTP or SOCSK. A prerequisite for writing – cURL’crawl constant.
- A little lower we find the line with the "request" parameter. Next, we indicate the site that will be accessed through a proxy server.
- Last step – specify the period of time required to send the request. If, in practice, the send time exceeds the timeout you specify, the request goes into the "failed" category.
Everything. This completes the setup of mobile proxies to work in cURL. From now on, all cURL network connections will go through the proxy server.
Choose mobile proxies correctly
Today, a huge number of companies providing proxy services operate on the market. Moreover, there are also free services, but their reliability is of great concern. To choose the right product, first of all, you need to focus on such a moment as anonymity. Yes, transparent cURL proxies will pass the request through themselves, but here is the user's real IP address will still be visible. Therefore, you should look for a product that guarantees the anonymity of the work. In this case, the fact of using mobile proxies will be visible, but the user's real address is securely hidden.
Proxies operating on SOCSK5 protocols have a high level of anonymity. In addition to the anonymity of the IP address itself, they will even hide the fact that the work is being done through an intermediary server. private paid mobile proxies are endowed with a high level of anonymity. Here, a personal channel with unlimited traffic is allocated for each user. It is they who should be given preference when choosing a proxy for working in cURL.
