Unfortunately in this sector of retail, our target audience is very fickle, and an abundance of similar online retailers in recent years have made this an extremely competitive market. We cannot afford to aggravate any customers at this point. In addition, a large proportion of our customers have little or no previous IT experience and cannot be expected to apply patches no matter how trivial it may seem to us! ***SNIP*** > The problems you describe with 5.01, I have seen when SSL keepalive > settings were enabled on the web-server.

So this particular problem must lie elsewhere. I'll agree with peoples' comments on IE5 being terrible, but unfortunately as an online retailer we have no choice as to what our customers access our website with, and a disturbing number of customers (33%) happen to be using IE5.00 to 5.01. If anyone else has any comments, they would be very much appreciated at this point! > You can check your SSL logs to see if the keepalive settings are active > - it they are you will see an incrementing number associated with each > request from the same user that indicates the SSL negotiation was > short-cut, and that previously negotiated keys are being used. > > 'nokeepalive' is fractionally slower, but at least your users will not > get the regular 'page cannot be found' issue. > > As to sharing Client Certs between IE and NS - we do this happily for NS > 4.0-4.75 and MSIE 5.01-6.0 without any issues. > > > Regards > Jeff > > > > > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED]] On Behalf Of Louis Sabet > Sent: 17 May 2002 13:29 > To: [EMAIL PROTECTED] > Subject: IE 5.00 - 5.01 SSL Connection Failures > > > Hi List, > > I work for a mobile phone retail company in the UK - www.mobiles.co.uk > > Recently we discovered that several of our customers were unable to > complete the secure portions of their orders.
