Icelink - "Cannot Connect To Server"

[ggrundy]

I have a topfield TF7100HDPVRtPlus.
The Icelink would not connect. I was constantly getting the message
"Cannot connect to Server".

Watching the network traffic with wireshark showed that I was actually connecting successfully to the sever
and retrieving the device information correctly!.

Further investigation revealed that contact via my Astaro Security Gateway was failing but contact directly was
succeeding.

The XML content being returned was identical in both cases
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.icetv.com.au/iceguide/PropertyList-1.0.dtd">
<plist version="1.0">
<array>
<dict>
<key>id</key>
<integer>0</integer>
<key>label</key>
<string>Lounge</string>
<key>manufacturer</key>
<string>Topfield</string>
<key>model</key>
<string>TF7100HDplus</string>
</dict>
</array>
</plist>

The only difference between the two pathways was in the http headers.

=====Direct from IceTv=====
HTTP/1.1 200 OK

Server: Apache/2.2.3 (Red Hat)
Vary: Accept-Encoding
Connection: close

======= Via Astaro Security Gateway=============
HTTP/1.1 200 OK

After adding icetv.com.au the the astaro "Transparent mode skiplist"
the problem was finally resolved.

I mention this here in the hope that others can avoid wasting the hours that this problem has cost me,
or what would be even better if the topfield engineers could look at making the icelink connection less fragile.

Wow, good pickup.  Maybe the Topfield baulks on the content-length field?  Or do you think it absolutely must have those headers in that order?

You will not be able to ping the www.icetv.com.au website (our hosting company blocks pings).
