Normalize URLs with extra slashes

[vidhiii1711]

Fixes #2067

This PR adds middleware to normalize URLs containing extra slashes
(e.g. //community// → /community/) so links and assets resolve correctly.

Includes tests to ensure correct redirects on www.djangoproject.com.

Hi there 👋,

I had some time and was browsing for reviews. I hope you don't mind me leaving some notes.

Cheerio!

Hi, thanks a lot for taking the time to review this and for the helpful suggestions!

I’ll update the implementation to simplify the slash normalization (likely using regex as you suggested) and reduce branching in the middleware.

I’ll also explore the try/except approach so the normalization only happens when a 404 occurs, keeping the common path fast.

Additionally, I’ll add a few adverse test cases to better cover edge scenarios.

Thanks again for the feedback — I’ll push an update shortly.

I have updated the middleware to normalize multiple slashes in the URL using a regex .

I also added a test case in test_www_urls.py to ensure that URLs like /community// correctly redirect to /community/ with a 301 status.

Please let me know if any further changes are needed. Thanks again for the guidance!

Slick solution! LGTM
