Setting a cookie through dispatcher

Question

I am trying to set a cookie through dispatcher and I using the below header

Header set Set-Cookie "currentCountryNames=Indian; path=/"

It works fine with static value, but I need to get the dynamic value through CDN(cloudfront) by using header HTTP:CLOUDFRONT-VIEWER-COUNTRY-NAME .

I tried this then

Header set Set-Cookie "currentCountryName=%{HTTP:CLOUDFRONT-VIEWER-COUNTRY-NAME}; Path=/"

but it did not worked it is giving syntax error

Unrecognized header format %;

Hi @varun790 You can try SetEnvIf CLOUDFRONT-VIEWER-COUNTRY-NAME "(.*)" COUNTRY=$1Header always set Set-Cookie "country=${COUNTRY}; Path=/; Expires=Thu, 01 Jan 2023 00:00:00 GMT" Note: The SetEnvIf directive requires the mod_setenvif module to be enabled in Apache. Ensure that it is enabled in your Apache configuration. Additionally, this assumes that CloudFront is forwarding the CLOUDFRONT-VIEWER-COUNTRY-NAME header to your origin server.

Hi @varun790

You can set a cookie with the value of the HTTP:CLOUDFRONT-VIEWER-COUNTRY-NAME header using expr syntax:

<If "%{HTTP:CLOUDFRONT-VIEWER-COUNTRY-NAME} != ''">
    Header expr Set-Cookie 'currentCountryName="%{HTTP:CLOUDFRONT-VIEWER-COUNTRY-NAME}"; Path=/'
</If>
