Can I block downloads of .txt files that are over a certain size

[erushforth]

I have been trawling the internet for an answer and as yet I cannot find a way to specifically block .txt files that are over a certain size.
Does anybody know if this is possible?

I have found that a regular expression can block file types but I cannot find a way to incorporate the file size part into this rule.

Any help would be appreciated.

Thanks

Squid has a traffic management page that allows you to specify a maximum download size, and have it apply only to specific file extensions such as txt.
