@sdmcraft EDS doesn't support url parameters in redirect source URL, I'll try to find any other way to deal with it rather than redirects.xls

Redirect existing tag page URL to the new format.

If query parameter based redirects are not possible then how would we solve the original problem i.e. having the right canonical url on the page?

If query parameter based redirects are not possible then how would we solve the original problem i.e. having the right canonical url on the page?

After the change, each tag page owns correct canonical url now. The problem is that we wanted to redirect current site tag page to the new tag page, let's say, Current tag page - https://www.sunstar.com/healthy-thinking/tag?feed-tags=germany New tag page - https://www.sunstar.com/healthy-thinking/tag/germany

In redirects.xls, the source URL doesn't support URL with parameter, we cannot use redirects.xls for the redirection. In my opinion, I don't think it's necessary, maybe we can ignore it.

@sdmcraft As we discussed, I've added the redirection for URL parameter tag page. Please have a check. https://github.com/hlxsites/sunstar/pull/576/files#diff-fbceb58f32b99b8a5309251f8c49ac8eda82fba58b905c600c92bce1ed2a1c8c
