Brief introductionof this talk:
Headers are a critical partof HTTP, and it has been shown that theyare increasingly subject to middleboxmanipulation. Although this iswell known, little is understood about thegeneral regional andnetwork trends that underpin these manipulations.
In thispresentation, I willexplain how we collected data on thousands ofnetworks to understand how theyintercept HTTP headers in-thewild, as well as how frequently HTTP headers aremanipulated by middleboxes, and the distinct trends we observed acrossdifferentregions and Autonomous System types. For example, weobserved a high number ofweb caching headers in poorly connectedregions such as Africa. Finally, theseoccurrencesusing worldwide socio-economic datasets are explained in details.
