What's the Maximum URL length in Firefox

[klane3162]

Can someone please tell me what the maximum URL length is in Firefox. Based on the following link, IE has set this max to 2083.

I thought that Browsers are required to support an indefinite length.

It appears that Microsoft has created this limitation in the browser and possibly email end of things. When I attempt to click on the mailto link in Firefox that is longer than 2083 characters does nothing. I'm guessing that's part of the limitation expressed in the reading of the URL link by Outlook. I can paste the 200+ emails into Outlook, or any other client and it will go just fine.

I tested a 33,000 character URL (long URI) and it worked fine in Firefox 1.5b1 (with Apache Tomcat as the server). All of the data was sent to the server correctly. It could probably go much higher.

As a side note, I found out that IIS 5 only supports around 11,500 character URLs.

Heh, here's the link, if you have Tomcat installed. 33,000 character URL

Firefox supposedly supports a URL length up to 2 GIGAbytes. I don't dare you to test that, though.

I'm beginning to think this is more of an email client limitation. I installed thunderbird, and tried making it my preferred email client, and it won't spawn a new mail message window when the number of characters in the email link exceeds 2083 characters. It appears that normal URL's work find at excessive lengths

You'd be pretty hard pressed to ever see a normal URL that big. Some of the giggest I have seen are places like E-bay when doing searches and the like

data URIs are URL's that contain the actual data in the URI itself. A data URI can contain an image or an HTML page or pretty much anything else. Here's one:
<a href="data:text/html;charset=utf-8,%3C!DOCTYPE%20HTML%20PUBLIC%20%22-%2F%2FW3C%2F%2FDTD%20HTML%204.0%2F%2FEN%22%3E%0D%0A%3Chtml%20lang%3D%22en%22%3E%0D%0A%20%3Chead%3E%0D%0A%20%20%3Ctitle%3ETest%3C%2Ftitle%3E%0D%0A%20%20%3Cstyle%20type%3D%22text%2Fcss%22%3E%0D%0A%20%20%3C%2Fstyle%3E%0D%0A%20%3C%2Fhead%3E%0D%0A%20%3Cbody%3E%0D%0A%20%20%3Cp%3Etest%3C%2Fp%3E%0D%0A%20%3C%2Fbody%3E%0D%0A%3C%2Fhtml%3E%0D%0A">This is a test</a>

Data URI's are an example of a case where the length of a URI can get very large, but Mozilla is the only browser that supports URIs larger than a few kilobytes. IE doesn't support the data: URI at all.

I got that 2GB number from here:

Thats fun, I could have some great fun making websites form one link.... (Joke although it would be a lot of fun).

Anyway, I can't even start to imagine a 2 Gigabyte sized URL, but its pretty impressive if Firefox can support that much.

Cheers and thanks for the information,
