The environment variable is set incorrectly

[ziaratban]

Hi

I want to control Access-Control-Allow-Origin header for multiple domains.

To do this, I make these settings:

1. Create Virtual host front
2. Create a static context with / URI
3. Set Rewrite Rules to :

RewriteCond %{HTTP:Origin} ^https?://(www\.)?(.*?example\.com3|.*?example\.com4)$
RewriteCond %{REQUEST_FILENAME} -f
RewriteRule . - [E=AccessControlAllowOrigin:%{HTTP:Origin}]

4. Set Header Operations to :

add Access-Control-Allow-Origin %{AccessControlAllowOrigin}e
set service-worker-allowed /

5. Map Virtual host front to a 443 Listener
   

What is happening?

In sometimes , lsws set incorrect AccessControlAllowOrigin value in response.
This mostly happens for font file requests.

Example

Request headers :

The wrong domain name https://sub2.example.com3 is likely coming from somewhere else.
Need to turn on debug logging see if it catch something.
