[squid-users] blocking mime types works for adobe, not for teams

[robert k Wild]

hi all,

i have in my squid config this

#deny MIME types
acl mimetype rep_mime_type "/usr/local/squid/etc/mimedeny.txt"
http_reply_access deny mimetype

mimedeny.txt

application/octet-stream
application/x-msi
application/zip
application/x-7z-compressed
application/vnd.ms-cab-compressed

it works as it blocks adobe reader download, but the url has an exe at the
end so maybe this is why

https://admdownload.adobe.com/bin/live/readerdc_uk_d_crd_install.exe

but it doesnt block ms teams from downloading

https://go.microsoft.com/fwlink/p/?LinkID=869426&clcid=0x809&culture=en-gb&country=GB&lm=deeplink&lmsrc=groupChatMarketingPageWeb&cmpid=directDownloadWin64

it just doesnt intercept the download at all and gives me the option to
"save file" its an exe

do you think this is because its a direct download link?

thanks,
rob
