Après avoir regardé le source code for mod_deflate je suis arrivé à la conclusion qu'il est impossible d'envoyer autre chose que gzip.
Maintenant, je ne suis pas un programmeur c
et je ne pense pas que je serai en mesure de commettre des correctifs moi-même ... mais de la source, je peux voir qu'il y a quelques choses qui doivent être corrigées (Attention, je n'ai jamais écrit de c ... donc tout cela est probablement terriblement faux)

}
return NULL;
}
/* update some code to define "preferred_method" */
/*
Update all code that references the string "gzip" to take
into account "deflate", and "zlib" as well.
This is the part I really have no clue how to do.
