Priority/Frequency: Major / Unknown

Vote Count: 3

Listed in the version 11.0.03.292480 Issues Fixed doc 
Problem Description:
Attempts to load a template with URL parameters limits output to first ~800 bytes, whereas the same template without URL parameters works correctly.

Only occurs when loading the default document - aka http://localhost/ (default document is index.cfm).

This also seems to be an issue with the IIS -> Tomcat connector with version 11, replacing the isapi_redirect.dll with the CF10 version corrects the problem.

Steps to Reproduce:
Load the following template in a browser, at the server root:

index.cfm:

<cfdocument format="pdf">
	hi from index.cfm
</cfdocument>



Actual Result:
When loading the default document WITHOUT any URL params (http://localhost/), the PDF is rendered correctly.  Inspecting the response shows Transfer-Encoding: chunked

When loading a specific template WITH URL params (http://localhost/index.cfm), the PDF is rendered correctly.  Inspecting the response shows 

When loading WITH URL params (http://localhost/?qwerty=1), the PDF content is truncated.  Inspecting the response shows that Content-Length: 832 and Connection: close



Expected Result:
Regardless of the content length/transfer encoding headers, the output should be the same to the client - an entire, intact PDF.

Any Workarounds:
Replace the CF11 isapi_redirect.dll with the CF10 isapi_redirect.dll

Comments:

I ran some testing on this and found the issue only occurs when the page name is not part of the URL. This also affect cfhtmltopdf. I have an example running on Windows 2012 at http://www.cfuser.com/coldfusion-11-bug-cfdocument/

Appears that this issue also affects using cfcontent when combined with cfheader type of content-disposition. Switching to the CF10 connector corrected the problem.

PDF was truncated when it was generated using the link with similar format like this: http://ip:port/default_document?query=string Fixed it.

We use a CMS that has permalinks for all pages. There is no index.cfm file behind an individual page. The bug stops us from being able to deliver files by cfdocument. I see that it is fixed, but I have the most recent updates and the bug is still there.
