HiI have a feature service being accessed via a proxy page so that it can be secured, and accessed using a dynamically generated token. (However, this problem appears to happen regardless of whether the service is secured - it's a proxy page issue).I am using the attachment inspector, out of the box in the Flex API. the problem is that new attachments do not hit the rest endpoint correctly. Instead of a standard response, I receive a string of HTML which represents the "Add Features" rest endpoint:
<html>
<head>
<meta http-equiv="X-UA-Compatible" content="IE=7" />
<title>Add Attachment (Feature ID: 420)</title>

<body>

So the POST which pushes an attachment to the endpoint is causing the service to respond with its HTML page prompt - as if the attachment data is not being delivered correctly.If I remove the proxy page and route the request directly, everything works correctly.I have stepped through the proxy page, and confirmed that the POST data does get transferred to the request to ArcGIS Server; it does seem to be pushing the bytestream across to the new request.I noticed though that the content type on the new request (inside the proxy) is defined as "application/x-www-form-urlencoded". However, the original content type posted from the Flex application is "multipart/form-data". I wonder if this is the problem - as it's binary data we're trying to push up as an attachment. I have briefly tried changing this to multipart/form-data in the proxy, but this causes the connection to close prematurely and the service request fails. I havent figured out why.Is there any further guidance here? Is there a known issue where attachments cannot be added via a proxy page connection?
