Methodology of REST API design
Koudelka, Jakub ; Burkoň, Lukáš (advisor) ; Jansa, Václav (referee)
This work deals with an analysis and design of application programming interface (API) within the architectural style known as REST (Representational State Transfer). Beginning of this thesis covers basic introduction of HTTP protocol and REST fundamentals, followed by analysis and solution proposals of common situations that can occur in API. Sample application was implemented by following these proposals.

Dynamic web pages
Kotlín, Jiří ; Kastl, Jan (advisor) ; Veselá, Bohumila (referee)
Serving dynamic web pages raises higher load of web servers and associated technologies. This can to some extent eliminate setting up reverse proxy with cache in front of the web server. The primary goal of this thesis is to implement this technique via presently most popular web server -- Apache. These Apache's proxy features were at first well tested and described, later practically applied in real LAMP software bundle enviroment (Linux, Apache, PHP, MySQL).

Methods for maintaining state information in the HTTP protocol
Polsemov, Anton ; Pinkas, Otakar (advisor) ; Šváb, Ondřej (referee)
This bachelor thesis is focusing on HTTP protocol, its features, and technological aspects. The HTTP protocol is stateless so it is necessary to search for methods to keep status information. These methods are cookies, URL query, session id, http authentication, hidden fields in forms, IP address and additional. Every method has its own strong and weak features. Security of these methods influences a final resolution. Ahead of description of the methods, the thesis is concerning cryptography a describing HTTP cookies in detail. The practical section contains an analysis of online banking in Czech Republic and characterization of trends in this brand. Also, an installation of a PHP5, HTTP Apache server, creation and signification of an OpenSSL certificate is in the last chapter and finally, a simple application of online Banking is created.

Methods for maintaining state information in the HTTP protocol
Fiurášek, Tomáš ; Pinkas, Otakar (advisor) ; Šváb, Ondřej (referee)
Interactive Web applications affect almost everyone of us. Communication in these applications is generally provided by HTTP protocol. This protocol is stateless, which means, that it doesn't recognize the relationship between individual transactions. In modern Web applications, however, maintaining the status is crucial to ensure functionality. This thesis deals with various methods of state transmission and storage which solve the fact, that HTTP is stateless. The first part describes a theoretical basis of the HTTP protocol, concerns history of the protocol and explains related concepts. Next chapter deals with proxy and cache servers that serve as mediators in the communication and outlines potential problems that can occur while transferring state information. The following section is devoted to the methods for the maintenance and transmission of state information. In this chapter I describe various methods, then I compare them and discuss potential difficulties. In the next chapter I present the possibilities of the implementation of those methods in different development environments. Given that the matter of security nowadays has the focus, I also look at several problems also from the angle of security and safety. Theoretical conclusions of this thesis are reflected in the enclosed web application, which practically demonstrates the discussed issues and proves that the author of this thesis not only understands those issues, but he is also able to apply them practically.

Server driven negotiation
Mikulka, Pavel ; Kastl, Jan (advisor) ; Pinkas, Otakar (referee)
Práce přibližuje základy protokolu HTTP a možnosti využití dynamického zasílání www stránek. První kapitola popisuje protokol HTTP na obecné úrovni, druhá se věnuje dynamicky zasílaným stránkám. Přínosem je ukázka implementace na dvou prakticky využitelných aplikacích. První z nich je automatický rozcestník pro webové sídlo, jehož úkolem je přesměrovat uživatele na nejvhodnější jazykovou verzi v závislosti na hodnotě hlavičky Accept-Language nebo IP adrese a druhou je download platforma pro společnost nabízející zábavní obsah pro mobilní telefony, jež poskytuje uživateli optimální verzi obsahu v závislosti na user-agent hlavičce jeho přístroje.
