Is there a way to block sitecore from creating the {website}#lang cookie?

I'm not sure if it's the same processor but you might try the follow which removes the site cookie.

<?xml version="1.0" encoding="utf-8" ?>
<configuration xmlns:patch="http://www.sitecore.net/xmlconfig/">
        <processor type="Sitecore.XA.Foundation.Multisite.Pipelines.HttpRequest.StoreSiteNameInCookie, Sitecore.XA.Foundation.Multisite">
          <patch:delete />
  • I tried what was suggested by both Michael and Marek. Looks like it better not to attempt this. Thank you! Jun 24, 2020 at 19:47
  • Adding my custom processor in the httpRequestProcessed pipeline has worked a treat to remove the [website]#lang cookies, much better than the httpRequestEnd pipeline I initially tried. May 20, 2021 at 1:25

As far as I know, {sitename}#lang cookie is set by the LanguageResolver processor.

There is a code

args.SitecoreContext.Language = lang;

And in the background, setter of the Language property of the context calls

  string cookieKey = site.GetCookieKey("lang");
  WebUtil.SetCookieValue(cookieKey, language.Name, expiryDate ?? DateTime.MinValue);

I haven't found any option to stop Sitecore from creating that cookie.

The only option would be to add a custom processor to httpRequestBegin processor after Sitecore.Pipelines.HttpRequest.LanguageResolver processor and in that processor remove the cookie from the response.
