Server behaviour9.7
404 page
Compression
- This website handles missing pages correctly by sending a 404 HTTP status code.
- This website was served with GZIP encoding. This is very good because it reduces the loading time of a web page.
- Adding or removing a trailing slash to all URLs of this site returns an error page (404). This is OK as no content is being duplicated, but visitors might try browsing to the pages of this website with or without a trailing slash. Ideally, the alternate URL should redirect to the correct page.
- Add a 301 redirect from the other version to the canonical URL.
- This website follows the best practice of using a permanent (HTTP 301) redirect from http://shodan.io to http://www.shodan.io. This is ideal.

- Add width and height attributes to all image tags. The width and height you specify should be the same as the source image. If you want to resize an image in the browser, use CSS.
