RE: multipart requests and file uploads problems on the Apache connection
You need tp use Ajp12 for multipart request servlets. Just specify something like this # # The following line mounts all JSP files and the /spqr/servlet/ uri to tomcat # JkMount /spqr/servlet/* ajp13 JkMount /spqr/servlet/LogoUpload ajp12 # Ajp13 won't handle the multi-part request properly JkMount /spqr/*.jsp ajp13 I believe there is a patch somewhere in the CVS repository, but seeing as we Upload Files once in a blue-moon, and the "slower" Ajp12 does the job, I haven't bothered. Never fix a running system!

That's interesting, since I've been doing that for some time now with no issues. -Original Message- From: Jose Euclides da Silva Junior - DIGR.O [mailto:[EMAIL PROTECTED]] Sent: Friday, December 08, 2000 03:20 PM To: [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: RES: multipart requests and file uploads problems on the Apache connection -BEGIN PGP SIGNED MESSAGE- Hi, everybody!

The code can be downloaded from O'Reilly's site www.ora.com I have only had one problem with it, and I think I have coded around it. The problem was that sometimes uploads from MSIE 5.01 Win do not send the boundary correctly (it varies by two characters everytime).

RE: multipart requests and file uploads problems on the Apache connection
Yes, this is a known bug in Ajp13. It looks like a fix is under development and should be available in the next release. Until then, use Ajp12. -Dave > Sandy McPherson wrote: > > Looks like the Ajp13 is screwing up!
