Hi ,
   Recently we reconfigured our site to only allow users port 80(www) access through a proxy server.  Since we have done so, dreamweaver cs3 does not preview images any more in design mode.  The links for certain are all good; they open in browser successfully.

Has anyone had any similar issues / workarounds for this?  I see absolutely no configuration parameters within cs3 to configure anything beyond ftp proxy.

CS3 doesn't have anything beyond the FTP proxy, but that shouldn't matter for Design view.  Unless your images are called with src="http://whatever..." Design View should pull your images from the Local Site folders and not the remote.

Hi ,  thank you for the response.  The images that the programmers are inputting are indeed as you mention "http://xxxxxx", which is where I'm having the problem.  CS3 simply wont preview them.

You take the machine temporarily outside the corporation where the proxy is not required and it will work fine

In the Site Definitions, what happens if you specify port 80 in the URL?

Okay.  

Design View in CS3 must be using a different port, so if they close off all other ports except for 80, there may not be anything you can do to fix it except to not use full URLs in the image src paths.

I find it's definately using 80, which is the only thing required to pass through the proxy.  HTTPS/443 traffic is not required; so as a test we used https://XXXXX, and it works.  

Again, it only works because the firewall allows 443 from any IP address.  Have you ever seen CS3 behave this way?  Its just as if it wont use a proxy server at all..

I haven't tried to use DW with a proxy for a long, long time.  If I'm ever in these situations, I just make sure I'm using relative paths and Design View works on the local site without any screwing around with ports and secure servers.  Setting up a local testing server is also a good way to just bypass the need for a proxy config...all you have to do is check in a file and transfer it to the remote site location and you're done.

I do know that proxy support in general is lacking in Dreamweaver.  FTP proxy sort of works, but WebDav sort of doesn't and there are lots of little issues that crop up continuously.

It might be that the newer versions of DW do this better natively.  CS4 uses a different rendering engine in design view (webkit) and CS5/5.5 support Live View.  If possible, download the free trial for 5.5 and see if it works any better.
