Does anyone have a clue as to what the problem may be???
Malformed multipart POST -Re: Malformed multipart POST -How do you parse the multipart POST request? Which server-side technology are you using?
Re: Malformed multipart POST -Hi, we are using Apache 2.2.21 if that is what you were inquiring about.
Re: Malformed multipart POST -I'm not sure we can help, we never had this issue. We have Apache too here. We've many users with PHP, ASP.NET, ColdFusion, JSP and they never report about this. issue.
Re: Malformed multipart POST -My user has been encountering this problem for a while:
I hit this problem again just now, and the Java Console may have some useful info – I tried uploading the NX syslog to PR 6817216 and although the tool reported the upload completed: Uploading : bowden1e6c098a.syslog (310,395 bytes) Upload started ...Upload completed ---------------------------------------------------------------------------------------------- Uploading : NX85_user_VM_Master.dpv (1,927 bytes) Upload started ...Upload completed ---------------------------------------------------------------------------------------------- After the user has upload the data, the bowden1e6c098a.syslog file has not been processed on the server. The java console output below, shows a warning. The cgi script that is supposed to be executed after the upload never gets triggered. This seems to only happen to this one user. Any ideas? and the java console shows: Java Plug-in 10.7.2.10 Using JRE version 1.7.0_07-b10 Java HotSpot(TM) Client VM User home directory = C:\Users\bowden ---------------------------------------------------- c: clear console window f: finalize objects on finalization queue g: garbage collect h: display this help message l: dump classloader list m: print memory usage o: trigger logging q: hide console r: reload policy configuration s: dump system and deployment properties t: dump thread list v: dump thread stack x: clear classloader cache 0-5: set trace level to <n> ---------------------------------------------------- [INFO] MApplet - JFileUpload 2.8 Build FINAL.001 [INFO] HTTPTransfer - Auto-detect proxy settings (ps): DIRECT [INFO] HTTPTransfer - Auto-detect proxy settings : host = null [INFO] HTTPTransfer - Auto-detect proxy settings : port = -1 [INFO] HTTPTransfer - Head Status code = 200 [INFO] HTTPUploadTransfer - Upload (POST) started : C:\Temp\bowden1e6c098a.syslog [INFO] HTTPUploadTransfer - Upload Status code = 200 [WARN] HttpMethodBase - Going to buffer response body of large or unknown size.

What server side script are you using? PHP or JSP or?
Re: Malformed multipart POST -The apache log reports the mulipost warning, the java console report the other warning. They both happen when the users tries to upload a file and it reports that it successfully uploads when it really doesn't. We are using perl cgi and apache.
