Una tarea HTTP(S) comprueba una única dirección URL para la disponibilidad, el rendimiento, el contenido adecuado, los errores y los vínculos rotos. Es compatible con solicitudes POST y GET, cookies, envíos de formularios, encabezados personalizados, sitios protegidos por contraseña (autorización básica HTTP/HTTPS, así como mecanismos de autorización de cookies/script) y umbrales de tiempo de espera. La tarea HTTP(S) admite la supervisión de los protocolos IPv4 e IPv6.

Las tareas HTTPS pueden validar certificados de seguridad, comprobar la entidad de certificación, comprobar la caducidad y enviarle recordatorios cuando se acerca la fecha de caducidad del certificado.

Una vez que haya creado un dispositivo y esté agregando o editando una tarea HTTP(S), se le pedirá que ajuste los siguientes ajustes.


Enter the URL of the page you wish to perform the task on. It should be formatted as such: www.example.com.

You can turn on a visually friendly input mode by clicking the Detailed switcher on the top of the section.

SSL/Certificate Check for HTTPS task

Secure Socket Layer SSL Certificate Monitoring is a standard aspect of HTTPS monitoring.

For an HTTPS task, the following additional options are available:

  • Authority: verifies whether a certificate chain contains a root certificate that is trusted, or not trusted.
  • Common Name (CN): validates that an address you navigate to matches the address certificate the address was signed to.
  • Date: verifies the certificate expiration date.
  • Revocation: validates that the certificate’s chain of trust doesn’t contain a revoked certificate.
  • Usage: verifies a certificate chain for the improper use of an intermediate certificate.
  • Expiration Reminder in Days: a reminder that notifies (as an error) about certificate expiration.
  • Client Certificate: client certificate name.

Tiempo de espera de finalización (en segundos)

Enter the number of seconds the task should wait for a response from the web page before ending the task and returning an error. If this is left blank the default timeout for a task is 120 seconds.

Tipo de solicitud

You can send a GET or a POST request to the web page. Selecting a GET request will simply retrieve data from the web server.  Selecting a POST request indicates that you are including a set of data for the server to act upon.  Note:  if you set the request type to POST but do not specify a POST parameter in the additional parameters section below, the POST value will default back to get upon saving the task.

Validación de contenido

Content Validation Keywords are used to ensure that the expected content was loaded onto a web page.

In the Keyword fields, you can specify one or more words or phrases that you wish to search for in the web page content.  If the expected keywords are not found, the task will return an error.

You can enter multiple strings into the keyword fields.  The values you enter can be separated by logical expressions as follows:
]} – keyword expression end;
{[ – keyword expression start;
() – grouping brackets;
& – logical AND;
| – logical OR;
! – logical NOT;
“string” – a keyword;

A successful keyword expression must include the start and end brackets as follows:


Autenticación básica

Basic authentication is used to allow users to access content on some websites.

Username: contains a username for HTTP/S basic or digest access authentication.

User Password: contains a password for HTTP/S basic or digest access authentication.

Read the article on Authentication username and password for more information.


The option allows to add any additional custom headers in the following format (by “=” symbol, each header should start from a new line):

Header_name_1 = "value"
Header_name_2 = "value"

Header Name: specify the name of the parameter as it will appear in the request.

Value: enter the value associated with the name of the parameter.

User-Agent header used by the Dotcom-Monitor HTTP task: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; .NET CLR 1.1.4322; .NET CLR 1.0.3705).

However, the IE6 user string can be replaced with any other string. To do this, add a custom header with the name “user-agent” and the specific value needed.

Opciones de registrar datos para solicitudes de publicación

If Post request type was selected you can specify the following Post parameters:

  • Name: the name of the parameter as it will appear in the request.
  • Value: the value associated with the name of the parameter.

Read the article on Authentication username and password for more information.
