Header conditions

This section shows the steps to configure header based condition.

Typical use-case is, you would want to pass all the bots requests to sera.n7.io .
Here, you can achieve it by providing all Bot patterns by setting the value of user-agent request header.

Note: Header conditions will work only on request-headers.
For demo purpose, we will be using example.com domain as an example. Here, we will only be using googlebot and bingbot user-agent for simplicity.

Prerequisite#

1. You must have a domain configured on Nitrogen.

Steps#

1. Click on Settings menu, and open Header Conditions tab.
   

2. Click on Create button.
   You will now be taken to a screen to provide header details.
   

   1. Group Name: Provide short name about the header condition.
      For example , you can provide a meaningful name like Sera Bots.

   2. Header Name: Enter the request-header name as user-agent
      

   3. Header value: Enter a regex expression here that should be matched for the required bots to be passed through SERA.
      For example, (?i)(googlebot|bingbot|yandex|baiduspider|facebookexternalhit|twitterbot|rogerbot|linkedinbot|embedly|quora\ link\ preview|showyoubot|outbrain|pinterest/0.|pinterestbot|slackbot|vkShare|W3C_Validator|whatsapp|redditbot|applebot|flipboard|tumblr|bitlybot|skypeuripreview|nuzzel|discordbot|google\ page\ speed|qwantify|bitrix\ link\ preview|xing-contenttabreceiver|chrome-lighthouse|telegrambot|google-inspectiontool)
      Note: By default header value match is case-insensitive.
      

3. Click on Save button. The configured pattern will be showed in Header conditions list.
   

You can now use this condition at many other places such as Condition Groups.
