help with uploading files in HTTPS

Hi,

I am running Apache 1.3.27 over win2k...
problem is that I have written a code in VB which lets the user
connect to the webserver using HTTPS ..the authorization is
alright..but when I try to upload a base64 encoded file...the response
from the webserver is error 414, URI too long...I dont know what to
do..!! The file is hardly 30 kbs..!!! Probably some configuration
parameter is to be added in httpd.conf which I am missing.

Other thing is.. before this problem happened, I was submitting the
encoded file as is..with the line feeds which are present after every
76 characters..when I used a perl script to retrive the value of the
parameter, I only get the encoding till the first line feed... this is
my POST request:

POST /org/PRACTICE1/dlg-add-toaspire?userId=ADMIN&p=r++E6YxEmSK7mInVBtc2g&serv ice=doc_add&content=datetime=200310302320&_f_objec t=encodedContentsOfTheFileWhichDOesntGetUploaded

Please help me asap! Deadline is near !!

Thanks !
