Hey all - I'm seeing what's probably some sort of bug in IE4, but if I can find a work around, it's save me a ton or arguing with people. The observation is that if I put a binary file into a Zope store (1.11.0pr1, with some CVS patches), i.e. anything with a mimetype that's not */text, I can't upload or download with IE4, through an Apache server. I have no problems with Netscape, but IE4 chokes - either upload or download. IE5 works. If I serve the same file from straight from Apache, it works fine. I used ZClient to grab the HTTP headers when served each way, but I can't seem to find a problem: This one works: server: Apache/1.3.6 (Unix) Debian/GNU content-type: application/msword accept-ranges: bytes date: Fri, 28 May 1999 21:26:19 GMT connection: close etag: "380b-3200-374eff5f" content-length: 12800 last-modified: Fri, 28 May 1999 20:41:03 GMT This one doesn't: server: Apache/1.3.6 Ben-SSL/1.32 (Unix) Debian/GNU vary: Authorization content-type: application/msword date: Fri, 28 May 1999 21:28:00 GMT x-powered-by: Zope (www.zope.org), Python (www.python.org) connection: close content-length: 12800 last-modified: Thu, 20 May 1999 22:48:17 GMT in each case, the file is downloaded correctly, by Client.py The only diffs are the accept-ranges:, etag:, vary:, x-powered-by: and last-modified: headers. Anyone have a clue? Ross P.S. where is the x-powered-by header generated? I can't seem to find it by grepping through the source. -- Ross J.
