Subject [users@httpd] Packet takes 42s to arrive in config with Apache Reverse Proxy
Date Thu, 19 Jan 2012 09:10:27 GMT

Use Case : access to JEE app running WL sometimes takes more than 40s  (no-ssl)
Config : Browser -- Apache 2.0 RP -- WebLogic 10

The response takes 42s to come back to the client. 

Intriguing is the HTTP header of the response received by the client (between brackets : time
stamp of packets on the client)

[ 12:31:26.277 ] - GET /mandates/extern/ HTTP/1.1  

[ 12:31:26.277 ] - TCP ACK 

[ 12:32:08.491 ] - HTTP/1.1 200 OK  
Date: Wed, 18 Jan 2012 11:31:26 GMT
Server: Apache
X-UA-Compatible: IE=EmulateIE8
Content-Type: text/html; charset=UTF-8; charset=UTF-8
Set-Cookie: JSESSIONID=VrTHPWtT398gwZwQdnQmkGQZxQMh5PPgGbtfGYf2KL1yJhgmBC9R!-1659218921; path=/;

Keep-Alive: timeout=10, max=496
Connection: Keep-Alive
Transfer-Encoding: chunked

So the date header lead me to think that WebLogic prepared the packet very quickly, so backend
processing seemed quick. But then at the same time, the timestamps of the Set-Cookie headers
are very intriguing since they directly refer to the reception timestamps. 

Question :
- could it be that Apache would manipulate the headers ?
- if not, am I right to conclude that WebLogic has prepared the packet immediately but delayed
the submittal until the back-end was ready and filled in the Set-Cookie headers ?

Many thanks !
