Question

cfcontent and "cannot be displayed because it contains errors"

I'm having an issue delivering an image using content.

I'm getting the following error when using cfcontent:  "... cannot be displayed because it contains errors".

Here is a sample of the code:

<cfcontent reset="true" file="C:\Storage\Sites\localhost\stars.jpg" deleteFile="false" type="image/jpeg" />

<cfabort>

Here's the odd thing ... If I access the coldfusion script directly; ie, http://localhost/test.cfm  it works just fine.

But if i'm doing any type of url rewriting through IIIS web.config it doesn't work; ie, http://localhost/test   (which through url rewrite would map to test.cfm). 

Any ideas anybody?

    If it works without the rewrite, I would first look at what might be wrong with your rewrite rules, not the CFML code itself, especially since the link to the file is absolute.  Can you post the entire error?

    I am not sure quite what you are trying to accomplish since you are using cfcontent to serve an image and then aborting, whereas a browser is perfectly capable of doing this on its own.  Perhaps you can provide further details.  The reset attribute is also ignored since you are specifying the file attribute.  This would not have a negative effect, just letting you know.

    In my examples, I was trying to simplify and troubleshoot things, but ultimately my code has all requests going through index.cfm as it's acting as a controller.  Here is my web.config

                    <rule name="general-1" stopProcessing="true">

                        <match url="^(.*)$" />

                        <conditions logicalGrouping="MatchAny" trackAllCaptures="false">

                            <add input="{REQUEST_FILENAME}" matchType="IsFile" ignoreCase="false" />

                            <add input="{REQUEST_FILENAME}" matchType="IsDirectory" ignoreCase="false" />

    <add input="{REQUEST_URI}" pattern="CFFileServlet/(.*)" ignoreCase="false" />

                        </conditions>

                        <action type="None" />

                    </rule>

                    <rule name="general-2" stopProcessing="true">

                        <match url="^(.*)$" />

                        <conditions logicalGrouping="MatchAll" trackAllCaptures="false" />

                        <action type="Rewrite" url="index.cfm?path={R:1}&{QUERY_STRING}" appendQueryString="false" />

                    </rule>

    If I change    index.cfm?path={R:1}&{QUERY_STRING}   to just index.cfm   the cfcontent tag works just fine, but unfortunately I need the rest of it passed through.
