Redirect Checker
Seamlessly analyze and track the complete path of URL redirects.
HTTP Headers
This tool allows you to view the HTTP headers of any website you choose, showing you exactly the information your browser receives when it connects to a server. Every time you visit a website or load a webpage, your browser communicates with the site’s server behind the scenes to request content and resources.
HTTP headers contain important metadata that the server sends back to the browser, including details such as response status codes, content type, caching instructions, security policies, and server configuration information. This data helps the browser understand how to correctly process and display the requested page.
Viewing HTTP headers can be especially useful for debugging website issues, analyzing performance, checking security-related settings, or understanding how a server is configured. This tool presents the header information in a clear, readable format, making it easy to inspect and interpret the data exchanged between your browser and the website.
Enter Website URL
We request the address from our server and show you what comes back. Only the headers are read, never the page, and nothing you enter is stored.
How to use it
The online http header viewer is a handy tool to retrieve the headers of a specified website.
- Enter the websiteEnter the website including http(s):// into the text field above. If you leave it off, https:// is added for you.
- SubmitBy clicking on ‘Submit’ the generator will request the header information from the entered website.
- Read the headersAll of the HTTP headers are then displayed in an easy to read format, with a check of the common security headers.
- If it is emptyIf the results are empty, the website might be offline or not available, please try again later.
Headers worth knowing
Cache-Control
Says how long browsers and CDNs may keep a copy. Long values make repeat visits faster.
Content-Encoding
Shows whether the page is compressed (gzip or br). Compressed pages download faster.
Strict-Transport-Security
Tells browsers to always use https for the site, which protects visitors on public Wi-Fi.
Frequently asked questions
What are HTTP headers?
Short lines of information that a server sends with every web page, before the page itself. They say whether the request worked (the status), what kind of file is coming, how long it can be kept (caching), and what security rules the browser should follow.
What do the status codes mean?
Codes starting with 2 mean success (200 OK). 3 means a redirect (301 moved permanently, 302 found). 4 means a problem with the request (404 not found, 403 forbidden). 5 means the server had a problem (500, 503).
What are security headers?
Headers such as Strict-Transport-Security, Content-Security-Policy and X-Content-Type-Options that tell browsers to apply extra protection. The tool checks the common ones and shows which are set. A missing header is not always a fault, but it is worth a look.
Why do I see several sets of headers?
The address redirected, and each step sends its own headers. With ‘Follow redirects’ ticked you see every step, with the last one being the page you would land on. Untick it to see only the first response.
What is the difference between GET and HEAD?
GET asks for the page as a browser would. HEAD asks for the headers only. A few servers answer HEAD differently, so GET is the closest to what a browser sees. Either way, this tool never downloads the page itself.
Why can’t I check some addresses?
Only public web addresses on ports 80, 443, 8080 and 8443 can be checked. Private network addresses such as localhost and 192.168.x.x are refused, and so are addresses that contain a user name and password.
Why does it say the certificate could not be verified?
The site uses https but its security certificate is expired, made for a different name or not trusted. Browsers warn visitors about this, so it should be fixed.
