Zip Archives downloaded from TWiki.org using IE are suddenly corrupted

This has not happened in the past. Yesterday I added a new plugin TreeBrowserPlugin, but everytime I upload the zip archive it cannot be downloaded successfully using IE. I verified that the zip archive is correct before upload. I verified that the archive can be downloaded successfully using wget .

Uploading is not broken, downloading is, as reported in PluginAddonsCorruptWhenDownloading.

Isn't this just PluginAddonsCorruptWhenDownloading ?

I bet you use IE. Try downloading the ZIP with Firefox, that worked for me too.

-- JosMaccabiani - 04 Sep 2005

Indeed. However, requiring download using Firefox is not a solution. This used to work, so we need to find out what has changed. It is not acceptable that one cannot download attachments from TWiki.org.

Downloading works fine from DevelopBranch (e.g., the attachment to TreeBrowserPlugin can be downloaded just fine from here.

Same issue when downloading the latest TWiki production release. This is something that needs to be fixed as soon as possible. TWiki.org does not leave a good first time impression if the TWiki package cannot even be opened. IMHO, fixing this issue has higher priority than any other server maintenance work such as increasing performance.

i just downloaded http://twiki.org/p/pub/Plugins/TreeBrowserPlugin/TreeBrowserPlugin.zip using wget and it unzipped fine. perhaps this is a linux vs. windows issue? i'll try to get access to a windows box later tonight to test that. i'll talk with sven on TWikiIRC and see if we can figure out what's going on (we don't know right now)

I confirm that download using wget works from a windows box also. It is download using IE that does not work. But you realize that this is the most wide-spread browser...

of course. i'm not trying to suggest workarounds; i'm trying to isolate the problem thanks for the additional information.

LynnwoodBrown suggested http://support.microsoft.com/default.aspx?scid=308090 i'm also evaluating http://archive.apache.org/gnats/3521 and http://archive.apache.org/gnats/1439

ok, problem "solved". sven turned off SetOutputFilter DEFLATE setting in apache. we would prefer to compress everything except already-compressed files. does anyone know how to do that?

-- WillNorris - 05 Sep 2005

http://httpd.apache.org/docs/2.0/mod/mod_deflate.html has all the docs on selective DEFLATE.
