Describe the Bug

While in development I am trying to use rewrites to proxy a local API server. The rewriting works flawlessly until the length of the URL reaches a certain length- in my case, 990 characters.

Expected Behavior

I'd expect the length of the URL to not impact when a rewrite occurs. Or at least, I'd expect the limit to be large enough to not interfere with reasonable URLs. In my case, I have URLs which need to include certain lengthy tokens (which I do not have control over). If this is intentional, it might be nice to print a warning while in development.

To Reproduce

I was able to reproduce in a fresh project (create-next-app) by adding a next.config.js like so:

module.exports = {
  async rewrites() {
    return [
      {
        source: "/:foo*",
        destination: "https://www.google.com/:foo*", // Can be any URL
      },
    ];
  },
};

Start the dev server and navigate to this URL, which is 256 characters:

http://localhost:3000/abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz

This should correctly direct you to google (albeit they don't have a page at this URL).

Now navigate to this URL, which is 282 characters:

http://localhost:3000/abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz

You should instead see a Next.js bad page error. So far as I can tell there is no "rewrite" happening (though I found this kind of difficult to debug).

Note - when creating a reproduction, the length of the URL which caused this issue was different (much shorter) than when I originally ran into the issue (using only localhost). Not sure what that's about...

Hi, this has been updated in v11.0.1-canary.3 of Next.js, please upgrade and give it a try!

Hi, confirming that after upgrading to v11.0.1-canary.3 the redirects work as expected. Thanks!
