I'm working on an data source tool for NCBI's Sequence Read Archive (SRA). I'm currently targeting a small form in the existing SRA application, to allow downloading a part of a specific assembly. The form I'm talking about is labeled "Alignment" on this page:

http://www.ncbi.nlm.nih.gov/Traces/sra/?view=run_browser&run=SRR445299

The application is not yet Galaxy-aware (but it will be). I'm currently telling that form to POST to GALAXY_URL, which is defined in the tool file as /tool_runner/sra-trace-download
It will essentially do the same thing as the "File" button in that form, except (of course) download to Galaxy. (A related question: will Galaxy tool_runner accept GET requests, or must parameters be POSTed?)

The file I'm using appears below. Instead of a download, I simply get the Galaxy home page content (welcome.html) in the center iframe, and no download.

Is it clear from the XML what I'm missing?

Thanks
