Reverse proxy of https traffic

[petr.spiller Profile]

Hi there,
we are running outside world server proxying all the traffic to the internal server. When using http all is good. When using https something goes wrong.
Is there any trick? The connection on the target server is dropped right after the initial TLS handshake. Both the server certificates - target and proxying IIS - are valid. I have been playing with Wireshark for days, however I'm not able to decipher the encrypted handshake message.

There are two scenarios (proxying server only accepts https request)
1) using RewriteProxy ^(.+)$ h_ttp://tisweb.ans.cz/$1 [NC,CR][/color] - data is passed as http request to internal server - OK
2) using RewriteProxy ^(.+)$ h_ttps://tisweb.ans.cz/$1 [NC,CR][/color] - data is passed as https request to internal server - FAIL

Any idea?

# Helicon ISAPI_Rewrite configuration file
# Version 3.1.0.94


# Registration info

RewriteEngine on
RewriteBase /
RewriteProxy ^(.+)$ https://tisweb.ans.cz/$1 [NC,CR]

Hello,

Generally, what is needed is on the server with ISAPI_Rewrite installed open Internet Explorer, go to back-end and confirm the certificate.
If it doesn't work, give the specific error you get.
