CFHTTP weirdness - Connection Timeout
Author: Andrew Grosset

sounds like you need to terminate the connection with CF
when the FINISH flag is returned irrespective of the content length....
I'm not sure how you'd do this with coldfusion but I'd imagine it was possible..
I hope you find the answer as this appears to be a very legitimate problem with
cfhttp.
Andrew.

Hi Jared
Did you ever get to the bottom of this. I've got the same issue with
CF9/IIS7/Vista.

In looking further at the headers, I've found that the content-length
header is not provided by the server I'm accessing. This shouldn't be
a big deal as the remote server indicates when the transmission is
done. But when the remote server sends the FINISH flag to Coldfusion,
CF does not terminate the connection as my web browser does. CF isn't
responding when the remote server terminates the connection. It
acknowledges the command, but doesn't actually close the connection
like it should.
This sure seems like a bug in CF to me. Is there any way around this
or any way to get CF to support the HTTP protocol correctly?

Thanks for your responses. No joy yet.

Tried this with an administrator account and the problem remains.

I'm assuming you mean <cfhttp result="myvar">. I've done that and then
<cfdump>ed the myvar variable. Everything looks fine (200 status code,
correct mime type, full headers) except Filecontent still shows
Connection Timeout.

Yes. I've tried VERY high numbers and no timeout at all. I should
note, that the full timeout period is used before I get anything on
screen. However, when I cfhttp to a file, everything runs and the the
file shows up almost instantly every time.
There's something breaking between when CF gets the remote data and
when it creates the Filecontent data.

Hi Jared,
Have you tried setting the timeout to a higher number?

Trying setting an explicit return variable to save into.

Thanks. This is so frustrating. This used to work fine, but suddenly
stopped a few months ago. I've even formatted, fresh reinstalled
Windows, and upgraded from 6.1 to MX 7 and the problem continues -
primarily with sites that provide that XML file. Other sites tend to
work fine.
Your exact code will execute the dump as follows for me:
Charset: [empty string]
ErrorDetail: [empty string]
Filecontent: Connection Timeout
Header: HTTP/1.1 200 OK Content-type: text/xml Pragma: no-cache
Cache-Control: no-cache
Mimetype: text/xml
Responseheader
[
Cache-Control: no-cache
Content-type: text/xml
Explanation: OK
Http_Version: HTTP/1.1
Pragma: no-cache
Status_Code: 200
Statuscode: 200 OK
]
Text: YES
I guess I could use CFHTTP to write the file to disk, then use CFFILE
to open it, but that is WAY more overhead than I want. I'd much rather
just get CFHTTP working like it's supposed to. :-(
Any other ideas?

I'm trying to use CFHTTP to capture a simple XML file from a remote server -
<cfhttp url="http://64.119.37.62/xml" method="GET" timeout="10">
When I try to access the #cfhttp.filecontent# is shows only
"Connection Timeout".
However, I can access the file from a browser on the server, the
cfhttp.errorDetail is empty, the cfhttp.statusCode is 200, the
mimeType is being picked up correctly, and if I sniff the packets I
see the entire file is send to CF. And if I set the path and file
attributes of CFHTTP, the XML file is saved successfully to my server.
So why is #cfhttp.filecontent# broken?
It only does this for some sites. With most of them, everything works
fine, but with this site and others like it, CF is choking on the
content somewhere.
I have tried setting the character set, setting user-agent, setting
the Accept-Encoding and TE headers to "deflate;q=0" to solve any
compression issues, and about everything else I can think of.
Can anyone else try to CFHTTP that file (http://64.119.37.62/xml) and
see if it works? This is a FRESH install of MX 7.
Frustrated!
Jared
