i'm working on a windows server 2008 ee, that uses apache 2.2.15 to make a netbeans project work through glassfish 2.1, to save data ina postgres 8.4 database. Such database saves data to a table that has 119 columns.

What i checked is that when i try to save a quite long URL

if i try to save this data within 30 seconds from the loading of the page, it works perfectly (it's even proved by the netbeans log, and even by actually checking the postgres tables that are changed).

Whenever i wait more than 30 seconds, i get error. i checked with these tools:

web console -> GET method undefined
httpfox -> NS_ERROR_NET_RESET
fiddler2 -> HTTP 1.1/504 responsefailed()
then i searched on the net and found this article, that says that probably the responsefailed error is dued to a 504 error.

So what i don't know is how to change the settings to make the connection last longer (5 minutes would be great). What parameter should be changed? which one: apache, postgres, glassfish?
