Is there a maximum size for a URL?

  • 772

What I am referring to is whether there is a limit to the number of characters a URL can contain, and what the value of that limit would be if there is.

    According to RFC2616 - protocol HTTP1.1, sec3.2.1

    The HTTP protocol does not place any a priori limit on the length of a URI. Servers MUST be able to handle the URI of any resource they serve, and SHOULD be able to handle URIs of unbounded length if they provide GET-based forms that could generate such URIs. A server SHOULD return 414 (Request-URI Too Long) status if a URI is longer than the server can handle

    There is no limit to that length. It depends exclusively on what each client and server support.

    Nevertheless:

    Note: Servers ought to be cautious about depending on URI lengths above 255 bytes, because some older client or proxy implementations might not properly support these lengths.

    It is recommended that this length does not exceed 255 bytes , so that it is fully supported by old clients or proxies ,

  2. The maximum length of the URL is variable, depending on the browser, for example in the famous Internet Explorer it is 2083 characters.

    Here is the data:

    Internet Explorer: 2,083 characters. Firefox: 65, 536 characters. Safari: 80,000 characters. Opera: 190,000 characters.

    and per web server:

    Apache: 4,000 carácteres
Microsoft Internet Information Server (IIS): 16, 384 carácteres.
Perl HTTP::Daemon: 8.000 caracteres.

    A little research doesn't hurt my friend.
