== Description of the problem ==
From a Phorge/Phabricator, mirroring an external Diffusion is somehow painful.
**Steps to reproduce:**
1. Go to your personal Phorge
2. Create a Repo
3. Add new URI · Mirror this: https://we.phorge.it/source/phorge/
4. Activate
**What happens:**
After the import is finished, the Monograms in the history of your mirror are broken. For example, that repo mentions `T1`, but it does not link to the upstream `T1` but to your local one, and they have nothing in common. This can be damn confusing and, in any way, it does not make the history very usable.
**What should happen instead:**
The links in the history must work. So, if the history mentions `T1` in a commit message, that must be resolved as a link to upstream, and not as a link to your nonsense unrelated local stuff.
**Current workaround**
As happened here on Phorge, it could be necessary to increase your local Task counter a lot so that collisions with your mirror could be avoided. But this has sense with new installations, not with every installation.
== Proposal n. 1 Option "Base Phorge URL" ==
(Whenever a Diffusion is mirrored or hosted)
In the URIs page, add this option:
| **Label** | Custom upstream base URL |
| **Type** | String |
| **Description**|You can set this value to the base URL of an external Phorge that is hosting this repository. If you add an URL, all references in commit messages (such as T1) will be rendered using that URL as base, instead of using your website. |
