[IP address blocking](https://en.wikipedia.org/wiki/IP_address_blocking) is one of the oldest
and most effective ways of preventing access to a website. It is therefore paramount for
a good web scraping library to provide easy to use but powerful tools which can work around
IP blocking. The most powerful weapon in our anti IP blocking arsenal is a
[proxy server](https://en.wikipedia.org/wiki/Proxy_server).
With Crawlee we can use our own proxy servers or proxy servers acquired from
third-party providers.
Check out the [avoid blocking guide](./avoid-blocking) for more information about blocking.
## Quick start
If we already have proxy URLs of our own, we can start using
them immediately in only a few lines of code.
```javascript
import { ProxyConfiguration } from 'crawlee';
const proxyConfiguration = new ProxyConfiguration({
proxyUrls: [
'http://proxy-1.com',
'http://proxy-2.com',
]
});
const proxyUrl = await proxyConfiguration.newUrl();
```
Examples of how to use our proxy URLs with crawlers are shown below in [Crawler integration](#crawler-integration) section.
## Proxy Configuration
All our proxy needs are managed by the <ApiLink to="core/class/ProxyConfiguration">`ProxyConfiguration`</ApiLink> class. We create an instance using the `ProxyConfiguration` <ApiLink to="core/class/ProxyConfiguration#constructor">`constructor`</ApiLink> function based on the provided options. See the <ApiLink to="core/interface/ProxyConfigurationOptions">`ProxyConfigurationOptions`</ApiLink> for all the possible constructor options.
### Crawler integration
`ProxyConfiguration` integrates seamlessly into <ApiLink to="http-crawler/class/HttpCrawler">`HttpCrawler`</ApiLink>, <ApiLink to="cheerio-crawler/class/CheerioCrawler">`CheerioCrawler`</ApiLink>, <ApiLink to="jsdom-crawler/class/JSDOMCrawler">`JSDOMCrawler`</ApiLink>, <ApiLink to="playwright-crawler/class/PlaywrightCrawler">`PlaywrightCrawler`</ApiLink> and <ApiLink to="puppeteer-crawler/class/PuppeteerCrawler">`PuppeteerCrawler`</ApiLink>.

</TabItem>
</Tabs>
Our crawlers will now use the selected proxies for all connections.
### IP Rotation and session management
&#8203;<ApiLink to="core/class/ProxyConfiguration#newUrl">`proxyConfiguration.newUrl()`</ApiLink> allows us to pass a `sessionId` parameter. It will then be used to create a `sessionId`-`proxyUrl` pair, and subsequent `newUrl()` calls with the same `sessionId` will always return the same `proxyUrl`. This is extremely useful in scraping, because we want to create the impression of a real user. See the [session management guide](../guides/session-management) and <ApiLink to="core/class/SessionPool">`SessionPool`</ApiLink> class for more information on how keeping a real session helps us avoid blocking.
When no `sessionId` is provided, our proxy URLs are rotated round-robin.

## Inspecting current proxy in Crawlers
`HttpCrawler`, `CheerioCrawler`, `JSDOMCrawler`, `PlaywrightCrawler` and `PuppeteerCrawler` grant access to information about the currently used proxy
in their `requestHandler` using a <ApiLink to="core/interface/ProxyInfo">`proxyInfo`</ApiLink> object.
With the `proxyInfo` object, we can easily access the proxy URL.
