                          |   | 3 | Trac supports a convenient way to refer to resources of other Trac servers, from within the Wiki markup. An !InterTrac link can be seen as a scoped TracLinks. It is used for referring to a Trac resource located in another Trac environment. A resource can be a wiki page, changeset, ticket or milestone.  |

                          |   | 25 | For convenience, there's also some alternative short-hand form, where one can use an alias as an immediate prefix for the identifier of a ticket, changeset or report, eg `#T234`, `[T1508]`, `[trac 1508]`. |

                          |   | 29 | It is necessary to setup a configuration for the InterTrac facility. | 
                  
                          |   | 30 | This configuration has to be done in the TracIni file, `[intertrac]` section. |

                          |   | 50 |  * If the targeted Trac is running a version below [trac:milestone:0.10 0.10]  | 
                  
                          |   | 51 |    ([trac:r3526 r3526] to be precise), then it doesn't know how to dispatch an InterTrac  | 
                  
                          |   | 52 |    link, and it's up to the local Trac to prepare the correct link.  | 
                  
                          |   | 53 |    Not all links will work that way, but the most common do.  | 
                  
                          |   | 54 |    This is called the compatibility mode, and is `false` by default.  | 
                  
                          |   | 55 |  * If you know that the remote Trac knows how to dispatch InterTrac links,  | 
                  
                          |   | 56 |    you can explicitly disable this compatibility mode and then ''any''  | 
                  
                          |   | 57 |    TracLinks can become an InterTrac link. |

                          |   | 76 | The generic form `intertrac_prefix:module:id` is translated to the corresponding URL `<remote>/module/id`, shorthand links are specific to some modules (e.g. !#T234 is processed by the ticket module) and for the rest (`intertrac_prefix:something`), we rely on the TracSearch#quickjump facility of the remote Trac. |
