Site served with www and without it

[jcsogo]

I have looked for a solution to this, but I haven't found any.

I have a blog that I serve as both www.domain.com and domain.com. As I don't receive many comments, I have just realized that if I use 'www.domain.com/article/' or 'domain.com/article/' I am served two different list of comments. I think that actually I am lucky and don't have comments in the same article in both www.domain.com and domain.com, but still I see no comments in one, and the comments in the other, depending on what is the URL I shared elsewhere.

Is there a way to tell remark that both directions are the same?

If one has to be set as the canonical, is there a way to 'migrate' and consolidate all the comments to one, wether it is www.domain.com or just domain.com?

Many thanks

Here is the URL migration doc, and you can alter the frontend configuration to use your URL with or without WWW on both locations using url param described here: by default, it equals to window.location.origin + window.location.pathname which is two different domains for the same page based on how user came to it in your case.

And aside from technical implementation from the fix, a domain that works the same on www and without it is a strange situation you usually avoid by setting up a redirect from one to another. Otherwise, the search engines wouldn't know which is primary and which is a duplicate. I wrote technical details on how to work around it here primarily because I understand that there might be a completely valid case of domain-per-region where you have pages with very similar content and it's preferable to keep comments synced between them.

Thank you for pointing out the right location of the documentation. About serving both www and non-www, I agree with you, and will try to change it. I haven't found the right solution for the redirection, based on the reverse-proxy solution I am using.

Nonetheless, I have tried to migrate everything to the site using www. So I have included this line within the frontend configuration script.

var remark_config = {
    host: "https://remark42.domain.com",
    site_id: 'site-id',
    url: "https://www.domain.com" + window.location.pathname,
    components: ['embed'],
    locale: 'es'
 };

With this I see that I lose the comments done in the posts without www, and the ones with the www remains, which is expected.

Then, I have tried to migrate the other comments using the following rules file:

https://domain.com/ https://www.domain.com/

The output from the command is the following - there are some errors, and nothing changes. Comments in pages with the www are served, while pages with comments on the domain.com (no www) are not.

Many thanks for your help.

You should add all links with comments one by one instead of doing a single rewrite: it doesn't rewrite the parts of URLs but looks for a full match to do the remap.

Also, that won't change how comments are served on a non-canonical version of the URL before you change the frontend configuration to set the URL explicitly to the canonical version, e.g., to www on a non-www site in your case.
