how to capture a specific substring from a variable's string value?(cmd or batch)

Question

I'm trying to escape some characters in a string. The string is constantly changing, for example Set-Cookie: SESSION=60a8245bc1976b40d0d8c4ff6f9784fc; path=/ I want to remove Set-Cookie: SESSION= and ; path=/ to leave 60a8245bc1976b40d0d8c4ff6f9784fc. But since it has "complex" characters, like : = / returns an error when i try

SET cookies2=%cookies:Set-Cookie: SESSION=%
SET cookies3=%cookies2:; path=/=%
echo %cookies3%

use a for /f loop to split the string:

@echo off
set "string=Set-Cookie: SESSION=60a8245bc1976b40d0d8c4ff6f9784fc; path=/"
set string
for /f "tokens=2 delims==;" %%a in ("%string%") do set "var=%%a"
echo -%var%-
