154798 - Proxy: "No proxy for:" field does not like hosts with numeric characters

Status: VERIFIED INVALID

Hi!

Seems to be bug interpreting the data found in 
Edit/Preferences/Advanced/Proxies, the field for "No proxy for".

If I type
 "macgyver"
..no proxy is used for macgyver. But If I only type "gaxtst21" or 
"macgyver,gaxtst21", it does not work. It used to work but it doesn't
anymore.

Is it perhaps because of the numeric caracters in gaxtst21?

Kind regadrs,
Marcus

I don't know. Can you try w/ a FQDN (gaxtst21.domain.com)?

It does work fine if I write gaxtst21 with the domain; e.g
 gaxtst21.bsstest.gbg.ehpt.com
(it's not visible outside ericsson). It doesn't matter if 
gaxtst21 is in "No proxy for".
In the tests with macgyver and gaxtst21 already described, 
I did not have anything else in this field.

"no proxy for" is intended as a list of domains.  in other words "no proxy for:
abc" would not prevent proxying to "abc.foo.com".

marcus,

can you please check what URL you are loading when you only have "gaxtst21" in
your "no proxy for" preference.  my suspicion is that you are either directly or
indirectly (via a redirect) loading http://gaxtst21.bsstest.gbg.ehpt.com/.

if you want to know for sure, you can enable these environment variables before
running mozilla:

  set NSPR_LOG_MODULES=nsHttp:5
  set NSPR_LOG_FILE=c:\http.log

then if you upload c:\http.log to this bug, we can determine exactly what URLs
are being loaded.

Hello,

They have rearranged the network lately. The file above is irrelevant.

I therefore cannot determine anymore if this error remains, is fixed or
was a complete misunderstanding from my point.

I have a recollection of testing it in IExplorer where it worked but this
was a couple of months ago, before the local DNS:es, network etc was changed.

Sorry for this,
Marcus

VERIFIED/invalid.

Can you recall what happened when you said "it didn't work?"

Darin is probably too busy to read the log right now, but from what I can tell,
you first attempt uses: 

http://gaxtst21

w/ no proxy, so that works correctly.

For some reason, that connection fails to work

so the browser goes back and tries:

http://www.gaxtst21.com

via a proxy, which responds w/ an error:

1752[f91010]:   HTTP/1.1 502 Bad Gateway

I've done some poking to verify the string matching works for numeric characters
as well. There might be a real problem that related to your config of that
system, but I think the original problem description is not a mozilla problem.

However, I did find this behavior curious, so I filed bug 190324.

I will make a hostname w/ characters a testcase in my proxy tests for "no
proxy", so if this is a real problem, we will catch it again before shipping
anything.
