See bug 159324.

So, marking it as duplicate of 159324 ?

I receive this error constantly on various sites, other browsers do not have any
problems.  Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.2b) Gecko/20021016

More information on one example, in case it helps to shed light on others...  I
have a site in ColdFusion that collects data in form fields and send it off to
the server for processing.  On submitting the form, the "no data" error happens
about 1/2 the time.  When I do not get the "no data" error, it all works fine. 
When I do get the error, my submission page runs consistently *9* times, as each
of the records ends up with 9 copies in the database, and Mozilla returns the
"no data" error, back on the data entry form.  (Then I submit again and end up
with even more duplicate records.)

Second, it seems that the error happens after the page has been sitting idle. 
Then after getting the error and trying again, the second time it always goes
through.

After installing the 1.3b release (2003021008) i got the "This document contains
no data" very often

Comment 5

[Misha Chitharanjan]

I too have been having this problem a lot since installing 1.3b.  I think it has
to do with advertisements being blocked by my hosts file, where the hostnames
are redirected to 127.0.0.1.  The alert messages are more annoying than the ads
were in the first place! Is there a work-around?

Comment 6

[Ray Gurganus]

I do have the following in my hosts file, but in the case I mentioned before,
there are not any ads or even any external sites being referenced.  So if the
host file is related to this case of the error, the problem is not related to
addresses in the hosts file...  or there may be multiple causes for the error...

127.0.0.1 banner.rootsweb.com
127.0.0.1 img.rootsweb.com

[Darin Fisher]

this may be related to bug 189965.  that bug is about misinterpeting connection
errors as TCP reset errors (i.e., "document contains no data" errors).  this bug
is possibly a duplicate, but marking as a dependency for now.

Comment 8

[Ray Saunders]

I get this problem in 1.3b on Windows NT when going to
http://americascup.yahoo.com/.  This problem does not appear on IE.

Comment 9

[Bernard Duffy]

I also have noticed this alert appearing since 1.3b. One affected site in
particular is www.drudgereport.com

Comment 10

I believe this is related to blocking ad servers via redirecting them to
127.0.0.1 in the hosts file.  While the issue was resolved in previous versions,
it seems to have come up again in 1.3 beta.  Now whenever a block site tries to
load, the error alert box pops up with "The document contains no data."

Instead of an alert box, a broken image should appear instead.

Comment 11

[Darin Fisher]

has anyone tested today's build?  does this bug still exist now?

Comment 12

[James Ausenbaugh]

I also am getting this error constantly after installing 1.3b.  I do have my
hosts file set up to redirect lots of adservers to 127.0.0.1.  I did not have
this problem in 1.3a, and do not have problem in other browsers.

Comment 13

[Darin Fisher]

James: yeah, that is a known bug in 1.3 beta (see bug 189965).  the problem
should be fixed when 1.3 final comes out.

Comment 14

[Carsten Klein]

This "bug" was first introduced by the 1.3b version.

It is a quite annoying error dialog, which can be experienced on the following
web-sites:

ebay.de / any of the article/auction listings
http://www.fawcette.com/dotnetmag/2003_02/online/lthe/default.asp

Comment 15

[Peter]

this is the url i used:
 http://www.fawcette.com/dotnetmag/2003_02/online/lthe/default.asp

when i went to the url, I had to hit "OK" many times.... I looked at the page
source to figure it out, and i found that on some banner ads, i have the servers
blocked...

I blocked them months ago. To block them, i went to my hosts file,
"C:\WINNT\system32\drivers\etc\hosts" in windows 2000, and added these 4 lines:
127.0.0.1 www.burstnet.com
127.0.0.1 ad.doubleclick.net
127.0.0.1 leader.linkexchange.com
127.0.0.1 z1.adserver.com

I tried taking out these 4 lines, and tried the page again. It worked! Because I
took out those 4 lines, I did not get the "alert: document contains no data" popup.

Some ad blocking programs do the equivalent of what I did to block those ads.
Maybe that causes it.

Comment 16

[Darin Fisher]

this is probably a duplicate of bug 189965, which has been fixed.  please reopen
if the problem persists with 1.3 final (or a recent nightly trunk build).  thx!

Comment 17

[Jon Wolf]

The bug still exists in 1.3b under WindowsXP Pro. One site that does it is
www.ticketmaster.com

Comment 18

[Jon Wolf]

ok, I did totally forget that my hosts file blocks a lot of ad servers and
redirects them to 127.0.0.1. I did rename the hosts file and I did not get the
error.
