Running Selenium RC with the *safari setting and the default proxy port 4444 work just fine.  However, I need to be able to run Selenium RC on several different ports at the same time.  I have been acheiving this with several other browser by using something along the lines of *custom E:\Tools\Chrome\Application\chrome.exe --proxy-server=localhost:4448 (this command is different for each type of browser).  Is there a command line option I can pass into *custom C:\Program Files\Safari\safari.exe ?? to use a specified port?

Thanks,

Jeremy
