wireshark - Capture a websites objects in separate pcap files -

a website consists of multiple objects (e.g. text file, few png files etc.), know if there's tool can capture individual requests/responses in different pcap files?

so example if browse http://somewebsite.com , , http://somewebsite.com consists of {index.html, image1.png, somestylefile.css, image2.png}, tool capture entire load of http://somewebsite.com generate {index.html.pcap, image1.png.pcap, somestylefile.css.pcap, image2.png.pcap}

i don't know of tool can this, or possible using scapy or similar?

a http connection can have multiple requests inside same tcp connection , browsers make heavy use of http keep alive. http pipelining requests/responses don't need separated in time, i.e. client can send request though response previous 1 not there. , http/2 data can interleaved, i.e. several responses transferred @ same time inside same connection.

insofar not possible capture data separate pcap file because might not separable @ packet level. if don't need original packet boundaries possible create separate pcap files each request not reflect original packets reflect application layer, i.e. response matching request.

one tool makes httpflow.pl can extract http/1.x requests/response pairs existing pcap (or sniff directly) , writes each request/response separate pcap file, if have been separate tcp connection. can clean data easier analysis, i.e. unchunk , uncompress http body.
