Squid limiting upload bandwidth

Hi !

I have a Linux server and squid 2.5 transparent proxy. I'm limiting
traffic with HTB and everything is working fine.
When someone on the network sends big file (webmail) over HTTP it takes
all upload bandwitch. I think how to solve this:
- limit with HTB, but this will limit all users (while one is uploading
others will work slowly)
- limit with delay_pools, posible but i want upload to be 2-3 time
slower than download
- set small value to request_body_max_size but it will block sending
files over HTTP which i don't wan't.

Does anybody know how to slowdown upload transfers through squid ?

Best regards
