jmjarvis -> RE: can't access oracle web forms (2.Apr.2003 10:41:00 AM)

Hey ieuan,
Have been doing a looooooooooooot of work on this lately as I've been having something similiar. All clients are web proxy clients.
After some serious netmon's I found two problems:
The first was caused by an Apache server sending back an incorrectly sized packet back to the ISA server. ISA passes this paket to the client but then instantly drops the session between itself and the Apache server. (This is by design I should add as ISA is correctly conforming to RFC2616 (HTTP 1.1) and the Apache server is not.) The client then sends a POST request to the ISA thinking that the session to the Apache server is still active. This obviously fails.
The second was Jinitiator. It has no concept of NTLM and from what I've heard Oracle are in no rush to provide this functionality. What happens here is the browser loads and authentication takes place as normal. Then when JInitiator loads it sends an anonymous request to ISA causing ISA to ask for authentication. JInitiator ignores this request and it sits there until the timeout is reached.
Both of these problems were fixed by installing the Firewall client.
This does 2 things - firstly because its the firewall service thats handling the request and not the web proxy service the incorrectly sized packets are not dropped. This should not be a long term solution to this problem as this lies with the web server.
Secondly authentication has already been taken care off between the client and ISA.
HTH
