Editing Query string (section)

== Compatibility issues ==
According to the [[Hypertext Transfer Protocol|HTTP]] specification:
<blockquote>Various ad hoc limitations on request-line length are found in practice. It is RECOMMENDED that all HTTP senders and recipients support, at a minimum, request-line lengths of 8000 octets.<ref>[https://tools.ietf.org/html/rfc7230#section-3.1.1 HTTP/1.1 Message Syntax and Routing]. ietf.org. Retrieved on 2014-07-31.</ref></blockquote>

If the URL is too long, the web server fails with the [[List of HTTP status codes#414|414 Request-URI Too Long]] HTTP status code.

The common workaround for these problems is to use [[POST (HTTP)|POST]] instead of [[GET (HTTP)|GET]] and store the parameters in the request body. The length limits on request bodies are typically much higher than those on URL length. For example, the limit on POST size, by default, is 2&nbsp;MB on IIS 4.0 and 128&nbsp;KB on IIS 5.0. The limit is configurable on Apache2 using the <code>LimitRequestBody</code> directive, which specifies the number of bytes from 0 (meaning unlimited) to 2147483647 (2&nbsp;GB) that are allowed in a request body.<ref>[https://httpd.apache.org/docs/2.2/mod/core.html#limitrequestbody core – Apache HTTP Server].
