If Bing provides an official API for accessing search results, it is recommended to use the API rather than scraping. Using an API is a more reliable and legal way to obtain search results.

Assuming you have reviewed and comply with Bing's terms of service, and there's no official API available, here's a very basic example using PHP and the file_get_contents function to scrape Bing search results:

This example simply fetches the HTML content of the Bing search results page for a given query. Keep in mind that web scraping is a delicate task, and the structure of the HTML might change, leading to your scraper breaking.

The maximum size of an RTP (Real-time Transport Protocol) packet when transmitted over TCP/UDP protocol depends on the payload size and the addition of RTP header information.

RTP is a transport protocol specifically designed for real-time applications like audio and video streaming. It is typically used in conjunction with UDP or TCP, as it does not provide its own transport layer.

RTP packets consist of two parts:

1. Payload: This is the actual data being transmitted, which can be audio, video, or other real-time data. The payload size is determined by the application or codec being used.

2. Header: The RTP header contains metadata required for the proper processing and synchronization of the payload. The header has a fixed size of 12 bytes. The maximum size of an RTP packet can be calculated by adding the payload size and the fixed header size:

Maximum RTP packet size = Payload size + 12 bytes (RTP header)

The payload size depends on the application or codec being used. For example, if you're using an audio codec that generates 100-byte audio frames, the maximum RTP packet size would be:

Maximum RTP packet size = 100 bytes (payload) + 12 bytes (RTP header) = 112 bytes

In the case of video codecs, the payload size can be significantly larger, depending on the video resolution, compression, and frame rate.

When RTP is used over TCP or UDP, the maximum size of the RTP packet is limited by the maximum payload size supported by the underlying transport protocol. For TCP, the maximum segment size (MSS) is determined by the MTU (Maximum Transmission Unit) of the network and the TCP header size. For UDP, the maximum packet size is limited by the MTU of the network and the UDP header size.

In summary, the maximum size of an RTP packet when transmitted over TCP/UDP protocol depends on the payload size and the addition of RTP header information, as well as the underlying transport protocol's limitations.

Getting a resident proxy for free can be challenging, as many free proxies are often unreliable, slow, or may pose security risks. However, you can try the following methods to find free resident proxies:

1. Proxy lists: Search for reputable proxy lists that provide a collection of free proxies. Be cautious when choosing a list, as some may contain malicious or unreliable proxies.
2. Online forums and communities: Look for online forums or communities where people share and discuss free proxies. Be cautious when using free proxies from these sources, as they may not be reliable or secure.
3. Social media: Some users may share their free resident proxies on social media platforms. However, be cautious when using proxies from social media, as they may not be reliable or secure.
4. Web scraping tools: Use web scraping tools to extract proxy information from websites that list free proxies. Be cautious when using this method, as it may be against the terms of service of some websites.

Please note that using free proxies can expose you to various risks, so it's essential to be cautious and aware of the potential dangers. If you're unsure about using a free proxy, it may be best to avoid them and opt for a paid proxy service instead. Paid proxy services typically offer better reliability, speed, and security.

When using a proxy, Google Chrome warns the user about it at startup. To connect directly, you must disable proxies at system level. That is, go to "Settings" Windows, then - "Network and Internet", in the section "Proxy server" disable the corresponding item.
