I use a T-mobile data service from time to time, but they insist on compressing data that looks like images. This causes SETI@home workunit downloads to be compressed, which makes them unusable.

It would be nice if workunits were downloaded with a tamper-proof secure connection, such as HTTPS.

Is there a method I can use to set these HTTP request headers that the SETI apps make?

Pragma: no-cache
Cache-Control: no-cache

You can set:

Skip image file verification?
Check this ONLY if your Internet provider modifies image files (UMTS does this, for example). Skipping verification reduces the security of BOINC.

- it's designed exactly for problems like yours.

Find it at the bottom of your Computing preferences - set it for each 'venue' where it might be needed.

I'm not sure that's what he ment:

So the question is, are just the immages causing issues or are really the workunits affected? The workaround posted by Richard works of course only if just images are recompressed by T-mobile.

Ralph isn't showing any errored tasks at the moment, so we'll have to wait until he comes back and can give us further details (such as a link to an example so we can read the full error message).

It's certainly possible for a task download to fail with a download error, but when you look at it in detail you see 'couldn't get input files', and looking further still, it's the slideshow images for the simple view, or something like that. They seem to be re-downloaded at every work fetch.

I know two people that are having data problems on verizon, it has to do with data compression I believe. They were able to duplicate the problem consistently.

Can you describe exactly what their problem was? (with error messages, if at all possible)
