Abstract

The publication presents the results of empirical research on technologies used in the home pages of the Irish credit institutions authorized under Irish Legislation to carry on banking business in the state according to the Irish Credit Institutions Register, Section 1 (a) in 2017. The home web pages of 10 banks were studied. Our survey reveals some interesting details about the proportion of the used web technologies. The average home page size is around 1.4 MB and the share of the images is around 50%. The share of other technologies is as follows: JavaScript programs - around 30%, CSS files - 9%, Font files - 8%. The size of the main HTML file is only 3% of the size of whole web page. The average total number of requests that the web browser makes in order to display the home page is around 71 separate requests - 23 requests for images, 21 for JavaScript, 9 for CSS files, 3 for Font files. None of the surveyed web sites are using HTTP/2. All of them are using as minimum HTTP 1.1. Near 40% of the sites are using 1 year-long Symantec SSL certificate. Web server settings for the Keep-Alive parameter vary from 5 to 15 seconds timeout for the opened network connection with maximum of 100 served requests.
