A possible problem then arises when the served page contains absolute URLs for resources, links etc which no longer use the .exit notation, and so could be fetched from a different exit. How often that would happen is open to question.<br>Another Privoxy rule could be written to rewrite those page URLs I guess, but how would you pass the name of the required exit to the rule?<br><br>GD<br><br /><hr />Lauren found her dream laptop. <a href='http://www.microsoft.com/windows/choosepc/?ocid=ftp_val_wl_290' target='_new'>Find the PC that’s right for you.</a></body>
