82947 - Exclusions in hosts file result in unecessary Alert dialogs.

Status: VERIFIED DUPLICATE of bug 28586

(Core :: Networking, defect)

Description

[Jerry Rowe]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; WinNT4.0; en-US; rv:0.9) Gecko/20010505
BuildID:    

I have entries in my "hosts" file such as this:
127.0.0.1    ad.doubleclick.net

Which short ciruit the loading of the ads.
On Netscape 4.7x, no error is notices.
IE 5 shows a message in place of the ad: "The page cannot be display"

Both of these are acceptable.

However Mozilla brings up a dialog box:
"Alert
The connection was refused when attempting to contact ad.doubleclick.net"

This is annoying as there may be a half dozen of the errors on a page and the
instance of Mozilla might be behind several other windows.



Reproducible: Always
Steps to Reproduce:
1. Modify hosts file with an entry as shown in description.
2. Load Mozilla
3. Load a web page with the exclusion.


Actual Results:  Dialog box(es) showing:
Alert
The connection was refused when attempting to contact ad.doubleclick.net

Expected Results:  Load the web page with no dialog box. Maybe show on the web
page, an error.
Preferably, through configuration, show nothing at all and maybe reformat page
absorbing the unused space.

[RFE] Should use error page, not dialog, for inaccessible pages (placeholder)

This will do for now.
