C3550 Switch PAC file question

[gbeginnerg]

Hi I have a CISCO CATALYST 3550 works as a layer 3 switch. And I got some PCs behind it. The PCs have PAC files configured and there are static IP routes set on the C3550 Switch.

Here's my question: Does PAC file only works for TCP flow and IP routes only works for UDP flow? 

I have checked multiple cisco support websites and community and didn't seem to be able to find an answer for that. Thanks!

PAC files hosted on Server like any other web Server, so that file will be pulled by the clients using http request, so its TCP stream.

(PAC file i take as Proxy PAC file for the Client to use proxy Server and download PAC file?)

Thanks for replying. Yes, PAC file is the proxy PAC file. I might not make myself clear. What I want to know is whether a proxy PAC file on a client PC is able to work for both tcp and udp flow on PC. Or it can only affect the tcp flow, and not the udp flow.

Same goes for the IP routes on a Layer 3 Switch, can IP routes work for both tcp and udp flow or just for udp flow?

Thanks!

http traffic only rely on TCP - that is short anser - http not rely on UDP.

ip route nothing to do with TCP or UDP, its just routing where to look destination IP address based on the routing table.
