URL redirection with environmental variable

[wssen]

I want to do a redirection in Apache2 web server with the below way:

When I type the URL : ""http://sub.mydomain.com"" in the browser, It should get redirected to ""http://localhost:8080/?var=varvalue""

I am new to apache2 server configuration and appreciate your help with the details of files and tips to be updated.

Thanks in advance.

what version of apache are you using?
this may sometimes affect the precise solution so make sure you refer to the correct documentation for your version.

you will need to use the mod_rewrite module for this.
you can test the hostname using a RewriteCond directive with %{HTTP_HOST} as the TestString.
then you can use the environment variable in the Substitution string of the RewriteRule directive by doing something like this in your target's query string:

...?var=%{ENV:EnvironmentVariableName}

That's assuming you really meant "environmental variable" and not simply "query string". This is far from the first time a topic header points in a different direction than the post body :)
