We have designed "C-HTTP" which provides secure HTTP communication mechanisms within a closed group of institutions on the Internet, where each member is protected by its own firewall. C-HTTP-based communications are made possible by the following three components: a clientside proxy, a server-side proxy and a C-HTTP name server. A client-side proxy and server-side proxy communicate with each o...

Recently, the largest concern for corporate owners of World Wide Web servers is how to minimize the response time, which ultimately is concerned of how quickly information can be displayed at a customer’s local monitor. In order to minimize the response time, a new efficient file transmission technique for World-Wide-Web, called web file transmission by Object Packaging, is proposed. The protot...

As of February, 2015, HTTP/2, the update to the 16-year-old HTTP 1.1, is officially complete. HTTP/2 aims to improve the Web experience by solving well-known problems (e.g., head of line blocking and redundant headers), while introducing new features (e.g., server push and content priority). On paper HTTP/2 represents the future of the Web. Yet, it is unclear whether the Web itself will, and sh...

EDITOR’S NOTE Geopersia is published biannually by the College of Science, University of Tehran, Iran. The College of Science published “Journal of Science”, which covered all fields of basic science, from 1968 to 2010. It was then decided that the College’s journals should be more specialized, and hence publication of Geopersia was launched. Geopersia aims to publish peer-reviewed original...

We focus on two distinctive features of HTTP-based C&C traffic by analyzing HTTP activity sets. First, C&Cs show a few connections at a time (low-density). Second, contents within a request or a response change frequently among consecutive C&Cs (content-change). Based on these two features, we propose a C&C analysis mechanism that detects unknown HTTP-based C&Cs with low false-positives.

The HTTP/1.1 protocol is the result of four years of discussion and debate among a broad group of Web researchers and developers. It improves upon its phenomenally successful predecessor, HTTP/1.0, in numerous ways. We discuss the diierences between HTTP/1.0 and HTTP/1.1, as well as some of the rationale behind these changes.
