Hi!

I have some trouble using STUNNEL on WIN98 to secure connections
to HFS (Http File Server), and hope, somebody can help me.

I can connect to HFS with the Browser (Firefox 2.0.0.3, IE 6.0,
on the same machine HFS is running, an other one in LAN and a third via
internet) and download files, bat every downloaded File is corrupt.

In most cases, transfer seems to terminate normally, but the downloaded 
file ist to short, sometimes there is popup, that tells me, that the 
file could not be read, because the connection is broken.

The log file shows the following:

My STUNNEL.CONF looks like this:
********************************
; File with certificate and private key
cert = stunnel.pem
key = stunnel.pem

; Log (1= minimal, 5=recommended, 7=all) and log file)
; Preceed with a ";" to disable logging
debug = 5
output = stunnel.log

; Some performance tuning
socket = l:TCP_NODELAY=1
socket = r:TCP_NODELAY=1

; Data compression algorithm: zlib or rle
compression = zlib

; SSL bug options / NO SSL:v2 (SSLv3 and TLSv1 is enabled)
options = ALL
options = NO_SSLv2

; Service-level configuration
; Stunnel listens to port 443 (HTTPS) to any IP
; and connects to port 44300 (HFS) on localhost

[https]
accept = 0.0.0.0:443
connect = 127.0.0.1:44300
TIMEOUTclose = 0
