How to block mime_types by https with Squid?

I have this rule to block extensions:

acl bl_ext url_regex -i "/path_to/bl_ext.txt"
http_access deny workdays bl_ext

Example content file “bl_ext.txt”:

.avi((a-zA-Z)(0-9)*)?(?.*)?$
.m4a((a-zA-Z)(0-9)*)?(?.*)?$
.m4r((a-zA-Z)(0-9)*)?(?.*)?$
.m4v((a-zA-Z)(0-9)*)?(?.*)?$
.mid((a-zA-Z)(0-9)*)?(?.*)?$
.mov((a-zA-Z)(0-9)*)?(?.*)?$
.mp3((a-zA-Z)(0-9)*)?(?.*)?$
.mp4((a-zA-Z)(0-9)*)?(?.*)?$
.mpeg4((a-zA-Z)(0-9)*)?(?.*)?$
.mpeg((a-zA-Z)(0-9)*)?(?.*)?$
.mpegps((a-zA-Z)(0-9)*)?(?.*)?$
.mpg((a-zA-Z)(0-9)*)?(?.*)?$
#etc, etc, etc

And this rule to block mime_type:

acl bl_mt rep_mime_type -i "/path_to/bl_mt.txt"
http_reply_access deny bl_mt

Example content file “bl_mimetype.txt”:

^audio/mp4$
^audio/mpeg$
^audio/wav$
^audio/.wma$
^audio/x-midi$
^audio/x-mp3$
^audio/x-mp4$
^audio/x-mpeg$
^audio/x-mpegurl$
^audio/x-ms-wma$
^audio/x-pn-realaudio$
^audio/x-pn-realaudio-plugin$
^audio/x-scpls$
^audio/x-wav$
^video/
^video/3gpp$
^video/avi$
^video/flash$
^video/flv$
^video/mp4$
^video/mpeg$
^video/mpeg4$
^video/ogg$
# etc, etc, etc

But these rules only work with http. Not with https.

Additionally I tried with these rules that I found on the internet and neither:

acl video rep_header Content-Type video/.*
acl audio rep_header Content-Type audio/.*
http_reply_access deny video
http_reply_access deny audio

I know that https traffic is encrypted and cannot be seen, however I ask:

Is there any way to block file mime_type or file extensions in Squid in proxy-cache mode (Not transparent – intercept) coming over https (without using SSL Bumping)?
