The FilterProvider syntax has changed in Apache 2.4

[xchs]

I recently upgraded my Apache web server from version 2.2.21 to 2.4.2 and while testing the Contao 2.11.5 hotfix branch I am getting server errors complaining about a syntax error regarding the FilterProvider directive (that we are currently using in our .htaccess.default server configuration file):

FilterProvider takes three arguments, filter-name provider-name match-expression

In fact, the syntax for the FilterProvider directive has changed in version 2.4:

mod_filter: FilterProvider syntax has changed and now uses a boolean expression to determine if a filter is applied.

However, the solutions actually discussed in the html5-boilerplate GitHub tracker do not look quite promising at all (apart the fact, the mod_version module fairly sure not being available in all hosting environments, I guess). Do we really need to do a version compare as proposed there in the ticket?

Does anyone know a better way we could handle this issue (maybe before rolling out the upcoming bugfix release 2.11.5)?

Funny you are mentioning it, because I also came across the issue this weekend :)

I am curious what they chose as their preferred solution, although I don't like the idea of having the same block three times (twice if mod_version is available and one legacy block). I'd rather have a htaccess.default.2.2 and a .htaccess.default.2.4.

I'd rather have a htaccess.default.2.2 and a .htaccess.default.2.4.

Yeah, that might be an alternative (meanwhile). However, we would have to maintain then four copies of the server configuration file, two with the default configuration and another two for the developing stage.

Adjusted the .htaccess.default file accordingly in 371d5a3.

In the H5BP .htaccess server configuration file was added a more general compression configuration for Apache (see a36b296)

It seems they entirely dropped the FilterProvider syntax. Does this work with Apache 2.4?

[xchs]

They claim so, yeah. See h5bp/html5-boilerplate#1012 (comment) and the corresponding pull request.

Cool :)
