While looking into net-proxy/webscarab, I noticed that the HOMEPAGE listed does not exist. This is the first result a search engine returned, and might be more suitable: https://www.owasp.org/index.php/OWASP_WebScarab_Project
https://www.owasp.org/index.php/Webscarab might be a better alternative (found from browsing owasp.org)
Fixed in CVS.
