HttpOnly Cookies
For fun, I was copying the “wordpress_logged_in_” cookie on one of my sites so I could manually set it in another browser and log in without going through the authentication step.

On small screens this big image is loaded but scaled down to display properly. The important thing to note here is even if the image is only displaying […]

Generally, these attempts are not targeted at the site specifically but instead are part of a huge automated attack. People want to hack into “a WordPress site”, not necessarily “your WordPress site”. These people […]

Google Indexing 301 Redirect
While SEO is not my focus of expertise, it is an interesting field which impacts the work I do. I was surprised when fellow developer Dustyn Doyle pointed out to me that Google was indexing 301 redirects. Based on my research, I couldn’t find any of these 301 redirect links coming up in general searches; […]
