Response: Technical Specifications

Siteimprove Response monitors servers' HTTP-requests at a certain distance and sends to predefined URLs. The Response module monitors a website's server(s) response and if required, the content of the response. If the response time exceeds the limit defined by the customer, we will notify you immediately via e-mail and/or text message. This article is intended to outline the technical specifications in regards to Siteimprove Response.

IP Addresses and User Agents

The IP address and user-agents used by Response can be found in the article "What IP addresses are used by Siteimprove?" (login required). We recommend you add all Response location IP addresses to your allow list to avoid the monitoring server being blocked.

Scan Type

HTTP content scanning: GET request for the HTML is sent and parsed along with positive or negative matches are evaluated. 

Server Locations

It is possible to select a preferred monitoring server location, however, your checkpoint URL can be checked from a different location if the preferred location server is unavailable.

Monitoring servers are available worldwide.

• Australia
• Sâo Paulo
• Frankfurt
• Mumbai
• Ireland
• Tokyo
• Singapore
• Seoul
• Northern California
• Northern Virginia
• Oregon

Alerts

Alerts are triggered by the following events:

• If no response to the HTTP request within the time configured
• The response status differs from 200 (Follow Redirect on 301 and 302 can be used as allowed set up)
• If the content scanning is enabled and finds no positive match or the entered negative match is found
• If a login is required and this fails
  

Users can be alerted via email and/or text message.

Any number of users can configured to receive alerts.

Custom Check Options

• Check rate of either 30 seconds or 1, 5, 15 or 30 minutes are provided
