Hi All,

I am using cntlm (version 0.35.1-1) proxy to talk to outside network. With the proxy configured properly, I am able to run:

" osc log prjname/pkgname" command and get the expected output.

But, when I run

"osc co prjname/pkgname" command, I get

Server returned an error: HTTP Error 502: Proxy Error ( The HTTP message includes an unsupported header or an unsupported combination of headers. )

I tried the above osc command with "-H" flag to check the HTTP headers. The failure occurs the first time, osc tries to download a file. From what I noticed, the header the proxy server is having a problem with is:

Content-Disposition: attachment; filename = "kiwi.spec"

Has anybody seen this problem? Is there a known workaround?

This header is for nicer web browser support when downloading a binary file. However, it looks like it is not really needed with the browsers I have tested. So we may can consider to remove it fro OBS 2.2. You can remove the header on your api server in app/controllers/build_controller.rb and test if it works. thanks adrian -- Adrian Schroeter SUSE Linux Products GmbH email: adrian@suse.de -- To unsubscribe, e-mail: opensuse-buildservice+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-buildservice+help@opensuse.org

Adrian,

I removed the following line from the definition of headers.update in /srv/www/obs/api/app/controllers/build_controller.rb file 'Content-Disposition' => %(attachment; filename="#params[:filename]}"),

This change doesn't seem to affect the headers returned to the "osc co" request.

right, that has only an effect when downloading the built packages ...

Also, I have access to two versions of OBS. One running 2.1.0 and the other running 1.6.0.

The response from the 2.1.0 version has " Content-Disposition: attachment" in the headers and the version 1.6.0 has ' Content-Disposition: attachment; filename = "kiwi.spec" ' (along with the filename) in the response.

The proxy server doesn't seem to have a problem with version 2.1.0. But the response from 1.6.0 is the one failing.

Uh, we don't support 1.6 since quite some time.... I can remember that we fixed a number of issues with proxies since then, but I would need to go through the quite long git history to find out more .... sorry, I can't remember anymore what we changed adrian

Weird of all, both the versions 1.6.0 and 2.1.0 have the same line for "Content-Disposition" header in build_controller.rb.

Thank you Praveen
