# Query String The query string is the part of a URL that contains the data to be sent to the web application. It generally includes fields added to the base URL by the client application, for example as part of an HTML form. ``` www.ejemplo.net/web.php?campo1=valor1&campo2=valor2 ``` The example above is for a dynamic website. In this case, the server automatically creates the response page when the browser requests it, using the data that appears in the URL. There are other methods of generating dynamic pages, such as separating the query strings using the “/” character. The server configuration lets us generate friendly URLs, like the one below: ``` www.ejemplo.net/main/blog/132 ``` In this case, the name of the variable is predefined on the server based on the variable’s position in the URL, and the content of the variable is its value (main, blog, 132). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.transparentedge.eu/getting-started/faq/glosario/query-string.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
