Hi, We made a program using mod_ssl 2.1.8 and https with Client Authentication - everything worked OK - with NS and with MSIE. Yesterday, we installed mod_ssl 2.2.4, but we found the bug with post method - as you described in the mailing list, so we installed mod_ssl 2.2.3 What happened - when we used HTTPS without Client Authentication - everything was OK. But when we used HTTPS with Client Authentication in NS 4.5 post didn't work (I/O error in security channel); In the MSIE the post method sometimes worked sometimes did not - in one page post worked in another page didn't work !?? Except this when we used https with Client Auth in NS we had to choose a user certificate two-three times. In MS we choose certificate only once but then we had to permit signing with cert private key two - three times. This does'n happen with mod_ssl 2.1.8. These are the options: SSLVerifyClient optional SSLOptions ExportCertData SSLRequireSSL Can somebody help us?
