Describe the bug
CookieRequestCache is used to save a request which contains an URL encoded query parameter. After restoring the saved request the request contains two values for this query parameter, the URL encoded and decoded form. If HttpSessionRequestCache is used, the query parameter is only present once, in decoded form.

Tested with Spring-Security 5.4.1.

To Reproduce

  1. Run the sample project
  2. Visit the url: http://localhost:8080/?goto=https%3A%2F%2Fstart.spring.io
  3. The output is: https://start.spring.io,https%3A%2F%2Fstart.spring.io

Optional steps to see the difference to HttpSessionRequestCache:
4. Change the used RequestCache in RequestCacheConfiguration to HttpSessionRequestCache (in the sample project)
5. Visit the url from step 2
6. The output is: https://start.spring.io

Expected behavior
The query parameter should only be present in decoded form. Therefore the output in step 3 should be https://start.spring.io.

Thanks for the detailed report @mengelbrecht!
This is fixed in 7f482ed and I will be backporting it to the 5.4.x branch as well.

Fix CookieRequestCache for URL encoded query parameters
1d96579 
Avoid populating the saved request parameters with encoded values. Since the query strings of the request and saved URL are compared and must be equal, we can just use the parameters from the incoming request.

Closes gh-9203
