Speedy Secure Responsive Web Design: SSRWD 12-Point Validation

By Web Developer Presidio Texas

Web Developer Presidio Texas presents a 12-point program for Speedy Secure Responsive Web Design (SSRWD) including HTTP/2 speed, HSTS security and W3C HTML5/CSS3 validation.


HTTP/2 (RFC 7540) is a major recent revision of the Internet World Wide Web’s HTTP network transport protocol based on the SPDY protocol originally developed by Góógle. HTTP/2 leverages multiplexing, server push, stream priority, header compression and other technological advances to significantly improve page load times and download speeds over encrypted connections. You can verify that your website supports HTTP/2 here:



The vast majority of all website traffic is generated from search engine queries. Most of that traffic flows to web pages with high visibility in organic search results – especially Góógle search rankings. Góógle, Bíng and other major search engines gives significant rank preference to web pages with speedy secure responsive web design. You can analyze the page speed optimization applied to your website here:



With concerns over Internet privacy at an all-time high, sites that are proactive about security will be the preferred product vendors and service providers. HTTP Strict Transport Security (HSTS) – the most reliable form of SSL/TLS encryption – helps protect website users from malicious hackers, ISP and third-party snooping, and unwarranted government surveillance. Proper HSTS deployment can be validated here:



Responsive web design is a web development methodology that allows web pages to be flexibly rendered in response to the screen size of the requesting device (e.g. desktop monitors, notebook PCs, tablet computers or smart phones). Responsive web pages adapt their layout to the viewing environment by using fluid grids, flexible images and CSS3 media queries. You can check your website responsiveness here:



Computer viruses, spyware and other malicious software (malware) is sometimes found embedded by hackers in the programs, web pages and downloads of otherwise trustworthy companies. Malware includes Trojan horses that may appear useful or attractive but have hidden functionality such as tracking to gather marketing statistics for spammers. You can verify the integrity of your web resources here:



Metadata is “data about other data”. Examples of metadata include META, Schema.org and other structured data tags embedded in the HTML source of web pages. Proper semantic optimization of web page metadata enables search engines to better understand and index the content of web pages, and consequently such web pages enjoy higher visibility in search results. You can evaluate your structured data here:



The World Wide Web Consortium (W3C) was established in 1994 to lead the Web to its full potential by providing the web developer with standards to promote its evolution and assure interoperability. Validating compliance with W3C HTML standards insures that all users (and bots, especially search engine spiders) have reliable access to the content and resources of your site. You can validate your HTML markup source here:



Cascading Style Sheets allow the separation of document content (HTML) from document format (CSS). The CSS language allows you to present the same markup page in different styles for different rendering methods. Validating compliance with W3C CSS standards insures that your content will be presented consistently and as intended across multiple devices and browsers. You can validate your CSS3 stylesheet source here:



The World Wide Web Consortium (W3C) Internationalization (I18n) Checker provides information about the internationalization features of a web page. It also summarizes key information about character encoding, language declarations, class/id names and request headers. Getting internationalization right saves time and trouble if you ever need to use your content in a language-sensitive way. You can access the I18n checker here:



Broken links present your site visitors, prospects and customers with roadblocks, detours and dead-ends that may cause them to question your competence and credibility. It may not seem like much on the surface, but a broken link can do serious damage to your reputation and your business. A single broken link can impact search rankings and user experience and/or result in lost clients and revenue. The W3C provides a link checker here:



RSS (Rich Site Summary; originally RDF Site Summary; often called Really Simple Syndication) uses a family of standard web feed formats to publish frequently updated information: blog entries, news headlines, audio, video. The World Wide Web Consortium (W3C) RSS validator is an attempt to codify the specification, make it easier to know when you’re producing RSS correctly, and to help you fix it if you’re not:



This Pingdom DNS checking tool tests delegation, nameserver, consistency, start of authority (SOA), connectivity and domain name system security extensions (DNSSEC) to verify that the DNS servers and settings for your website are configured properly. This assures that domain names resolve to the right IP address, that web page requests are routed and responded to correctly, and that emails are sent and received as intended:


Terlingua Web Developer Offers Leadership to the Big Bend Chamber of Commerce

Greetings All,

Terlingua Web Developer Offers Leadership to the Big Bend Chamber of CommerceMy name is Tim Shirley, and several years ago I purchased land in Brewster County with the intent of eventually relocating. Last March that relocation was completed when I settled into my current residence in the Big Bend Valley portion of Terlingua Ranch. Several things attracted me to this area, including the majestic landscapes, the pioneering community and the friendliness of the people. I am a long-distance motorcyclist and especially excited about the potential the Big Bend has as a destination for other riders seeking breathtaking views and ideal riding conditions.

I am originally from San Antonio. I am married and we have three lovely daughters and six grandchildren. My bride La Don currently works in Washington DC – but is working her way to ultimately join me here on Terlingua Ranch. I am happy that the Big Bend region offers so much for families like mine who enjoy tranquility, panoramic scenery and a wide range of outdoor activities.

I share all this with you because it is my understanding that the Big Bend Chamber of Commerce might be in need of significant organizational changes including new leadership. I am reaching out to you to express my interest and willingness to contribute in any way I can. In addition to my passion about the area, professionally I offer an extensive background as an entrepreneur and expert-rated web marketing technologist. Currently I am the principal of WLWeb.US, a web design, development and marketing firm headquartered here.

Prior to moving back to Texas, I lived in South Florida for 15 years. Over those years I was involved with several business networking organizations. So rest assured that if you hand me the reins of the BBCOC, it wouldn’t be my first rodeo. If you are looking for someone with the background and bandwidth to build a better chamber, I’d be honored to be of service and eager to shoulder the responsibility.


Tim Shirley 🙂

Websites (Like Ours) Leveraging Cloudflare CDN Just Got A Boost From HTTP/2!

By Web Design Fort Davis Texas

Web Design Fort Davis Texas explains how Cloudflare content delivery network (CDN) users get download and page load speed boosts from their HTTP/2 transport protocol deployment.

After more than 15 years, the Hypertext Transfer Protocol (HTTP) has received a long-overdue upgrade. In February 2015, the IETF HTTP Working Group approved HTTP/2 and its associated HPACK specifications. HTTP/2 is based on the SPDY protocol, which was first announced in November 2009 as an internal Góógle project to increase the speed of the web. And while still supporting SPDY, on 3 December 2015 Cloudflare introduced HTTP/2 support for all customers using SSL/TLS connections.

The main focus of both SPDY and HTTP/2 is performance, especially reducing latency as perceived by the end-user while using a browser, with a secondary focus on network and server resource usage. One major benefit of HTTP/2 is its ability to multiplex a single TCP connection from a browser to a website, or in the case of CloudFlare, a reverse proxy

HTTP/2 vs HTTP 1.1

Although HTTP/2 is based on SPDY, it has evolved and incorporated several improvements in the process. Nevertheless, it maintains many SPDY benefits:

  • Multiplexing and concurrency: Several requests can be sent over the same TCP connection, and responses can be received out of order, eliminating the need for multiple connections between the client and the server and reducing head-of-line blocking.
  • Stream dependencies: The client can indicate to the server which resources are more important than others.
  • Header compression: HTTP header size is reduced.
  • Server push: The server can send resources the client has not yet requested.

While the HTTP/2 specification does not require TLS, all major browser vendors have indicated that they will only support HTTP/2 over a TLS (“https://”) connection. And when HTTP/2 is active, you will see a blue lightning bolt icon near the right end of the web page address bar in Firefox or Chrome browsers.

So far, worldwide less than 3% of all website have been upgraded for HTTP/2. But that percentage is increasing daily. You can follow the development and rollout of HTTP/2 at the IETF HTTP Working Group HTTP/2 website or on Twitter @HTTP_2.

P.S. As a nose-thumb to the NSA, HTTP/2 opens every new connection it makes with the word “PRISM“.
