Squid only modifies the headers it is required to modify by HTTP, or if you configure specific modifications to happen (any *_header_access, *_header_replace, *_header_add directives in squid.conf). There is no such thing as "file" in HTTP - so no "file size" exists as such. If they mean some custom header, then Squid is definitely not altering it without config making that happen. There is a Content-Length header but that applies to the payload size of the message being sent. If that is what they mean , Squid does not alter it in valid HTTP traffic. They may be using it in invalid ways though which Squid is required to correct on sight. You can add "debug_options 11,2" to squid.conf to get a trace of the HTTP messages going through when SEPM does its update thing. I suggest only trying that in a period of low traffic.
