"Use a Checkstyle file accessible via HTTP" option does not support HTTP redirects such as 302 and 307 #682
Description
Using version 5.114.0 of the CheckStyle-IDEA plugin in Intellij IDEA 2025.2 (Ultimate Edition).
I attempted to use a download link to the "latest" version of a rules file, from a well-known repository manager system.
This failed - after clicking "next" on the Add Configuration dialog, I get "Loading the rule file caused an error" with the output below.
Pasting the link into the browser verifies that the address is valid and returns a correct rules file.
Downloading the file and loading it into the plugin via the "Use a local CheckStyle file" option works - this confirms the file is valid.
Accessing the download link using curl shows that the link is actually returning a series of HTTP redirects - codes 302 and 307 - which eventually take us to a link to a specific version, which then returns the xml file with an http response header of "application/xml".
So the question is - can the CheckStyle-IDEA plugin be changed so that it can handle HTTP redirects such as 302, 307 (possibly also others such as 301 and 308) on the url specified in the "Use a CheckStyle file accessible via HTTP" field?
