**Steps to replicate the issue** (include links if applicable):
* Navigate to a page with a link to a ZObject, for example https://www.wikifunctions.org/wiki/User:Msz2001/sandbox
* See what does it link to (e.g. `/view/pl/Z10000`)
* If it happens that the link leads to your language version:
** Change your interface language
** See that the link target doesn't change (e.g. links to PL even though you have English set)
* Purge the page
* See that the link target is now your interface language
**What happens?**:
The link targets are stored in a cache that's common to all users. The language code that's embedded in the `/view/LANG/Z10000` link is determined for the user who invoked a purge and then it's reused for other people, even if they have other language set.
**What should have happened instead?**:
Everyone should see a link that leads to a page in their own language.
