16 | DESCRIPTION |
| 84a4f22a |
17 | This is a simple Role which sets the response "Content-Type" to be |
| 778b6a5a |
18 | "application/xhtml+xml" if the users browser sends an "Accept" header |
| 19 | indicating that it is willing to process that MIME type. |

20 | |
| 84a4f22a |
21 | Changing the "Content-Type" to "application/xhtml+xml" causes browsers |
| 22 | to interpret the page as XML, meaning that your markup must be well |
| 23 | formed. |

25 | CAVEATS |
| 06cf3efb |
26 | This is useful when you're developing your application, as you know that |
| 778b6a5a |
27 | all pages you view are parsed as XML, so any errors caused by your |
| 28 | markup not being well-formed will show up at once. |
| 29 | |
| 84a4f22a |
30 | Whilst this module is has been tested against most popular browsers |
| 31 | including Internet Explorer, it may cause unexpected results on browsers |
| 32 | which do not properly support the "application/xhtml+xml" MIME type. |
| 33 | |

34 | METHOD MODIFIERS |
| 35 | after process |
| 36 | Changes the response "Content-Type" if appropriate (from the requests |
| 37 | "Accept" header). |

39 | METHODS |
| 778b6a5a |
40 | pragmatic_accept |
| 41 | Some browsers (such as Internet Explorer) have a nasty way of sending |
| 42 | Accept */* and this claiming to support XHTML just as well as HTML. |
| 43 | Saving to a file on disk or opening with another application does count |
| 44 | as accepting, but it really should have a lower q value then text/html. |
| 45 | This sub takes a pragmatic approach and corrects this mistake by |
| 46 | modifying the Accept header before passing it to content negotiation. |

48 | ATTRIBUTES |
| 49 | variants |
| 50 | Returns an array ref of 3 part arrays, comprising name, priority, output |
| 51 | mime-type, which is used for the content negotiation algorithm. |
| 52 | |
| 53 | PRIVATE METHODS |
| 54 | _build_variants |
| 55 | Returns the default variant attribute contents. |
