what is data crawling?

Data scraping and data crawling are two phrases that you often hear used , as if the two words are synonyms that mean the exact same thing.  Many people in common speech refer to the two as if they are the same process. While at face value they may appear to give the same results, the methods utilized are very different.  Both are important to retrieving data but the process involved and the type of information sought after vary in different ways.What Exactly is Data Scraping?Data scraping is the finding of data and then scraping it. It pulls data directly from a page. This doesn’t pull exclusively from the web, it can be taken from anywhere that data exist.  This could include spreadsheets, storage devices, etc, anywhere data exist in any form. Any  of the above doesn’t have to come from the internet or from webpages. It is the scraping of data, not the web.    This process is required for filtering and distinguishing different types of raw data from different sources into something that is useful and informative. Data scraping is much more specific in what it extracts than data crawling.  It can pull things such as commodity prices and more hard to reach information.  One of the minor annoyances of data scraping consist in the fact that it can result in duplicate data since the process doesn’t exclude this from different sources that it acquires it from.  Data scraping tools online are able to execute actions that data crawling tools are unable to accomplish including javascript executing, submitting data forms, disobeying robots etc.  I recommend checking these providers:Roxlabs provides business intelligence data, advanced agents and enterprise level support.

HTTPS PROXY WITH CURL

HTTPS proxy means that the client establishes a TLS connection to the proxy and then communicates over that, which is different to the normal and traditional HTTP proxy approach where the clients speak plain HTTP to the proxy.Talking HTTPS to your proxy is a privacy improvement as it prevents people from snooping on your proxy communication. Even when using HTTPS over a standard HTTP proxy, there’s typically a setting up phase first that leaks information about where the connection is being made, user credentials and more. Not to mention that an HTTPS proxy makes HTTP traffic “safe” to and from the proxy. HTTPS to the proxy also enables clients to speak HTTP/2 more easily with proxies. (Even though HTTP/2 to the proxy is not yet supported in curl.)In the case where a client wants to talk HTTPS to a remote server, when using a HTTPS proxy, it sends HTTPS through HTTPS.If the IP needs to be an e-commerce platform or social media, consider selecting roxlabs dedicated computer room IP. Fast IP, easy to set, unlimited traffic.More on:roxlabs

What is SSL and the Benefits of SSL Proxy?

What is SSL Proxy?The SSL proxiescontrol Secure Sockets Layer – SSL traffic -to ensure secure transmission of data between a client and a server. The SSL proxy is transparent, which means it performs SSL encryption and decryption between the client and the server.The SSL proxy also reproduces server certificates so the server can make a secure (SSL) or unsecure (HTTP) connection to a web server.What is an SSL Proxy Server?A proxy server is an intermediary between a user’s computer and the Internet. A user first connects to a proxy server when requesting web pages, videos or any data online. The proxy server then retrieves data that have been previously cached. If an entirely new request, the proxy server gets data from the original source and caches it for future use.A Secure Sockets Layer (SSL) proxy server ensures secure transmission of data with encryption technology. Security in an SSL connection relies on proxy SSL certificates and private-public key exchange pairs. SSL offload and SSL inspection features require the servers to share their secret keys to be able to decrypt the SSL traffic.How Does SSL Proxy Work?A key function of SSL proxy is to emulate server certificates. This allows a web browser to use a trusted certificate to validate the identity of web server. SSL encrypts data to ensure that communications are private and the content has not been tampered with.The SSL proxy does the following:• Acts as a client for the server by determining the keys to encrypt and decrypt.• Acts as a server for the client by first authenticating the original server certificate and issuing a new certificate along with a replacement key.• Decryption and encryption take place in each direction (client and server), and the keys are different for both encryption and decryption.• Hands off HTTPS traffic to the HTTP proxy for protocol optimization and other acceleration techniques.What are the Benefits of SSL Proxy?• Decrypts SSL traffic to obtain granular application information.• Enforces use of strong protocols and algorithms by the client and the server.• Provides visibility and protection against threats embedded in SSL encrypted traffic.• Controls what needs to be decrypted by using SSL Proxy.Crawl data Are the target websites American e-commerce and other websites.Try the U.S. data center agent: more than 40000 computer room IP, fast and stable.More information:roxlabs
