For any website, it is important to correctly configure HTTP headers. Many articles have been written on the topic of headers. Here we have summarized the accumulated experience and RFC documentation. Some headers are mandatory, some are outdated, and some can cause confusion and contradictions. We have created a checker for automatic verification of web server HTTP headers<\/a><\/noindex>. Unlike many other services that simply display headers, this service allows you to:<\/p>\n

    \n
  1. set the values for standard headers;<\/li>\n
  2. add your custom headers;<\/li>\n
  3. specify the HTTP protocol version: 1.0, 1.1, 2 (checks if HTTP\/2 is supported);<\/li>\n
  4. indicate the request method, timeout, and postdata to send to the server;<\/li>\n
  5. the checker also verifies the correctness of the responses to the If-Modified-Since and If-None-Match requests if the server response includes Last-Modified or ETag.<\/li>\n<\/ol>\n

    <\/a><\/noindex>
    \nWe do not claim to have the final truth. For specific content and individual projects, there may be exceptions. But this service will certainly point out what to pay attention to; you may find it useful to edit your headers. Below is a list of what the verification service pays attention to. To understand why, read     the articles on Habr<\/a><\/noindex>.<\/p>\n
