Why does CFHTTP return I/O Exception for a file path when trying to upload an image in Coldfusion?

Question

I'm running Coldfusion8 and have a cfc which handles image processing.

The cfc runs fine when grabbing images from external sources, putting them into a temp storage, resizing and saving to S3. I now tried to run a new set of images from manual uploads through this cfc and all of a sudden, I'm getting an error.

First I grab the image, store it in a temp directory and then invoke my img_handler:

   <cffile result="temp" action="upload" accept="image/jpeg,image/jpg" filefield="Dateiname8" destination="#variables.tempDirectory#" nameconflict="overwrite" />
    <cfset variables.testFilePath = variables.tempDirectory & temp.serverFile>

    <!--- catch CMYK --->
    <cfimage action="info" source="#variables.testFilePath#" structname="cmyk" />
    <cfif cmyk.colormodel.colorspace EQ "Any of the family of CMYK color spaces">
        <cfthrow type="FileNotFound" message="#tx_settings_icons_error_cymk#" />
    </cfif>
    <cfif structKeyExists( cookie, "resolution")>
        <cfset variables.screenWidth = cookie.resolution>
    <cfelse>
        <cfset variables.screenWidth = "na">
    </cfif>

<!--- call image handler --->
    <cfinvoke component="services.form_img_handler" method="upload" returnVariable="variables.worked">
        <cfinvokeargument name="cm" value="upload_background" />
        <cfinvokeargument name="pt" value="#variables.tempDirectory#" />
        <cfinvokeargument name="fl" value="#temp.serverFile#" />
        <cfinvokeargument name="se" value="#form.app_basic_id#" />
        <cfinvokeargument name="ar" value="background" />
        <cfinvokeargument name="ck" value="#variables.screenWidth#" />
        <cfinvokeargument name="gb" value="" />
        <cfinvokeargument name="ax" value="int" />
        <cfinvokeargument name="al" value="#variables.allow#" />
    </cfinvoke>

This works all right. The temp image is created and stored in the temp folder. My problem is when I try to read the image in my image_handler like so:

<cfhttp timeout="500" 
    throwonerror="no" 
    url="#LOCAL.tempDirectory##LOCAL.imgFile#" 
    method="get" 
    useragent="Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.8.1.12) Gecko/20080201 Firefox/2.0.0.12" 
    getasbinary="yes" 
    result="LOCAL.objGet">

This produces the following error:

catch - struct

Charset: [empty string]
ErrorDetail: I/O Exception: For input string: "\website\test\mem\secure\Innentitel.jpg"
Filecontent: Connection Failure
Header: [empty string]
Mimetype: Unable to determine MIME type of file.
Responseheader:  
[struct]
Statuscode: Connection Failure.  Status code unavailable.
Text: YES

I'm pretty much clueless what is happening here.

Questions
My application is running on SSL, but if I can grab the image in the first step and store it in the temp directory, why is it that I cannot pull it in from there again from my cfc. Could the problem be my upload function using access="remote" as I am also calling this function as a webservice? If so, what can I do to have my function handle both remote and regular requests?

Thanks for help!

EDIT:
To clarify, the cfinvoke in the first code block calls my cfc for handling all image uploads to Amazon S3. Inside this cfc I'm making the cfhttp call in question. Here is how I'm doing it now using cfimage, which forces me to do all my validation before calling the cfc.

<cfcomponent output="false" hint="image handler - s3 manager">

    <cffunction name="Init" access="public" returntype="any" output="false" hint="Initialize">
        <cfreturn true />
    </cffunction>       

    <!--- this is the function I'm calling --->
    <cffunction name="upload" access="remote" output="false" hint="creates images and stores them to S3">
        <cfargument name="cm" type="string" required="true" hint="original form submitted" /> 
        <cfargument name="pt" type="string" required="true" hint="img path" /> 
        <cfargument name="fl" type="string" required="true" hint="img filename" />
        <cfargument name="se" type="string" required="true" hint="user id" />
        <cfargument name="ar" type="string" required="true" hint="item id" />
        <cfargument name="ck" type="string" required="true" hint="screen width" />
        <cfargument name="gb" type="string" required="true" hint="item to send back something" />
        <cfargument name="ax" type="string" required="true" hint="remote call y/n" />
        <cfargument name="al" type="string" required="true" hint="allowed formats or def(ault)" />

So I'm now using cfimage to retrieve the image from the temp folder, which works fine vs. cfhttp. I had my image validation routine after the cfhttp call, which I now moved to outside of the cfc call. Not sure this is better/smarter, but at least it's working now.

You should be able to set your function access=remote, and access it both public and remote. I'm a little confused by the code. Is the 2nd block part of the method being invoked at the end of the 1st block? If you have the file in a temp directory now, I don't know that I see the need for cfhttp. I've never tried and can't right now, but can you confirm that cfhttp works with a url that is just a fully-qualified path, like it is here? According to the documentation, cfhttp will assume HTTP protocol if you don't specify anything. — Barry, Sep 25 '12 at 03:42
Thanks for the clarifcation on `access remote`. Regarding the above, I moved all my S3 file management into a serparate cfc, so I can access it throughout my application. I'm pulling in images and create a temp image on the server (to validate), then pass to my s3.cfc for storing. So the end of the first part invokes my cfc in which the second part sits....

cfhttp requires full URLs with protocol. A cursory glance at the error messages states ErrorDetail: I/O Exception: For input string: "\website\test\mem\secure\Innentitel.jpg".

If you convert it to a URL with protocol does it work?

I stumbled on that, too and checked the `#LOCAL.tempDirectory##LOCAL.imgFile#` which was just a "folder link" (E:/xyz/website...), so I hardcoded the URL (http://..), but it still did not work. The I/O error now was `I/O peer not authenticated`. I have been reading through [this](http://coldfusion.sys-con.com/node/623640/mobile), but I don't really understand why it's happening. My site is running on SSL, but this worked fine before, so I don't get what changed so it breaks now. I have fiddled something together with `cfimage` as a workaround, but I'm not really happy with it (validation-wise) – frequent Sep 25 '12 at 07:20

Why does CFHTTP return I/O Exception for a file path when trying to upload an image in Coldfusion?
