Re: HTML Generator/proxy using POST method
I have solved the problem by creating a custom generator based on
ProxyGenerator.java (from Lenya). The generator copies parameters and
headers from the original request to the proxy request, then it copies
cookies and headers back to the response.
This seems to work, with the exception that at least in Forrest, the
ResponseWrapper object passed to the generator via the objectModel map
does not allow modification of response headers and unlike
HttpResponse does not have the setStatus() method (sending Form data
via the POST method often results in a 'page temporary moved' and
redirection to another page). I don't know how to solve this problem -
i.e. dynamic redirection from inside an inner body-*, but this is
perhaps more Forrest specific.

This will not do as proxy, since there is no knowledge of the query
parameters available to place in the sitemap. Also, above constructs a
query string, which will not be used if the page is to be retrieved
using the POST method.

RE: HTML Generator/proxy using POST method
Hi Tal,
You can use the cinclude transformer with elaborate syntax to perform
more complex HTTP requests.
{url you want to access}
method
POST
{name}
{value or XML fragment}
But this DOES require that the url results XML not HTML.
Kind regards,
Geert

Re: how to load balance in a portal
Clustering can have negative performance implications. Also, some objects in Cocoon are not serializable and prevent clustering.

Apache httpd + tomcat 5.5.17 I found some resource about sticky session, still trying,tks. johnson Thomas Soddemann 提到: > Hi 許議中, > > which application container are you using? > Many application containers support clustering.

Re: how to load balance in a portal
Hi 許議中, which application container are you using? Many application containers support clustering. With their clustering facility you can keep session intact and I guess that's what you are looking for.

Re: how to load balance in a portal
I'm not sure this is the right list for your question as it is really about apache httpd. I can't really help you but I know our operations folks have configured our load balancer to use sticky sessions. Unfortunately, I don't know the details of how to do it though. 許議中 wrote: > Hi! > > I want to do a loadbalance in a portal because of heavy duty, I use > apache httpd to call tomcat, using balancer in workers.properties, it > really balance, but when I change from one coplet to another, it always > change the service server, and cause a 404 error or logout, how to avoid > it change server in the same session, or there's another way to do > crosss server session. > > Best Regards > > johnson > > - > To unsubscribe, e-mail: [EMAIL PROTECTED] > For additional commands, e-mail: [EMAIL PROTECTED] > > - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
