Query String
A part of a web page URL that passes data to the server, often used for search queries, filters, or delivering dynamic, customized website content.
A query string is the portion of a URL that comes after the question mark, containing parameters and values that pass information to your web server. For example, in the URL example.com/products?category=shoes&size=10, the query string is category=shoes&size=10. These parameters tell the server what specific content to display, enabling dynamic, personalised experiences without creating separate pages for every possible combination. Query strings are commonly used for search functions, product filters, tracking campaigns, sorting options, and pagination. Your hosting server processes these parameters and generates the appropriate response, whether that's filtering database results, customising content, or recording analytics data. Understanding query strings helps you create more interactive websites, implement effective tracking, and troubleshoot issues with dynamic content. They're an essential part of modern web development that bridges the gap between static URLs and dynamic, database-driven content.
