AdFilter breaks ftp proxying ?

[Tom Hageman]

(is this the right place to discuss problems with third-party OmniWeb plugins?)

In OmniWeb (3.0) with jamacht's otherwise excellent AdFilter (0.3.6a)  
plugin installed, I'm having trouble accessing ftp: URLs through a proxy  
http server.  That is, it seems like AdFilter or OmniWeb tries a hostname  
lookup of the ftp site first, instead of unconditionally passing the ftp:  
URL to the proxy server.  This fails on a machine that is locally  
networked to the system running the http proxy, and cannot connect to the  
internet to resolve host addresses. (the system running the http proxy  
also runs PPP, with just the single dynamic IP-address to share between  
the two machines -- it's a NeXT slab, so it can't do NAT or the like.  I  
prefer to run OmniWeb on the much-snappier Intel machine for obvious  
reasons...)

ftp proxying started to work again when I removed AdFilter and re-started  
OmniWeb, so I suspect the problem originates in AdFilter, or an  
interaction between OmniWeb and AdFilter.

Console log (with AdFilter installed):

Aug 16 19:05:29  ftp://ftp.icce.rug.nl/pub/tom (FTP): Host not found: No  
such host ftp.icce.rug.nl


For comparison, here is the Console log (with AdFilter removed):
