Use our server header check tool to quickly check HTTP response headers for any domain. Simply enter the URL and get started to check server headers.
More Tools
Our HTTP header checker lets you enter any domain name/URL and check its HTTP response headers. The headers contain information such as the security policy used to protect the website, the total caching time, etc.
The details stored in the HTTP header are essential for network admins and developers as it helps them understand the performance and security of a website.
Here is how you can easily use our server header checker to check the HTTP header of any domain.
Our header checker tool is straightforward to use. There are no complex processes you have to navigate, nor do you have to worry about entering any complicated lines of code. Specify the domain name, and our tool will handle the rest.
When checking the HTTP headers of a URL, here are some of the values that you can find along with their values.
Accept: This HTTP header tells the server about the types of content that the client can process.
Accept-Charset: This HTTP header is used to specify the character encoding method that the client can process/understand.
Accept-Encoding: This header is used to specify the content encoding method that the client can process and understand.
Authorization: This HTTP header is used to contain credentials and details for authentication purposes.
Cache-Control: This header is used to define the caching mechanism of the server for handling client requests and responses.
Connection: This header indicates whether the connection between the server and the client remains open or not after a transaction.
Content-Encoding: This serves to describe the encoding transformations that are applied to the body (e.g., gzip).
Content-Language: This header tells which natural language the content is in.
Content-Length: This header shows the size of the request/response in bytes.
Cookie: This HTTP header is used to send cookies stored on the client to the server.
Date: This HTTP header shows the date and time for the message (request/response)
ETag: A unique identifier for a resource version used for caching validation.
Expect: This header describes the expectations that the server must meet in order to process the request.
Host: This header is used to specify the domain name of the server (used in virtual hosting).
If-Modified-Since: With this header, the request only asks to fetch the content if it was modified after the specified date.
If-None-Match: This header requests the content only if the ETag doesn't match the cached version.
Origin: This header serves to identify the origin of a cross-origin request (CORS).
Referer: Provides the URL of the referring resource.
Server: Contains information about the server software handling the request.
Set-Cookie: Instruct the client to store a cookie.
Transfer-Encoding: Specifies the form of encoding used to transfer the payload safely.
User-Agent: Contains information about the client software making the request.
WWW-Authenticate: Indicates authentication methods required by the server.
You need to check the HTTP header of a URL to ensure it responds correctly to client requests. The header gives you helpful information on the URL response to incoming requests and the type of requests it is designed to receive and entertain.
This status means the URL has been permanently moved to a new address.
However, using our header checker will first show you the error and let you know that the URL has been moved. After that, it will show you the headers of the new URL.
If you don’t see any results for the entered URL, check the address carefully and ensure it is correct. If the headers are still not provided, try again after some time to rule out any temporary issues with the tool.
