Using "SSLVerifyClient required" with OHS Reverse Proxy Fails (Doc ID 465806.1)

Last updated on MARCH 17, 2020

Applies to:

Oracle HTTP Server - Version and later
Information in this document applies to any platform.


If the SSLVerifyClient directive is set to required and the requesting browser has an OCA certificate, the
browser never returns with any content. With the SSLVerifyClient directive set to optional or none, OHS behaves as expected.

The following may be observed in the Apache logs:

[Sat Jul 21 01:58:56 2007] [info] (70007)The timeout specified has expired:
SSL IO error, nzos_Read return 28862
[Sat Jul 21 01:58:56 2007] [info] NZ Library Error: SSL IO error [Hint: the
client stop the connection unexpectedly]
