Strap will detect Web proxy settings automatically by probing a bunch of web addresses with different settings.
It will report success or failure.
If proxy detection fails or to speed up the start of Strap:
Assume, the proxy host is proxy.organization.com and the port is 8080.
Rename the script file to.
"PH=proxy.organization.com PP=8080 more text if you like"
PH= and
PP= must be upper case. The separating spaces are important.
There must be no space at the equals sign.
