Too late when I sent this. Let me make the necessary alterations to
the nomenclature. Sorry!
web server = df. (WS)
app server = df. (AS)
request = df. req
response = df. res
----> = df. passing the control
With ResourceAction
1.0 WS req WS res HTML [2]
1.1 WS req ----> AS res [3]
1.2 WS req ----> AS res [3]
1.3 WS req ----> AS res [3]
1.4 WS req ----> AS res [3]
1.5 WS req ----> AS res [3]
1.6 WS req ----> AS res [3]
1.7 WS req ----> AS res [3]
1.8 WS req ----> AS res [3]
1.9 WS req ----> AS res [3]
1.10 WS req ----> AS res [3]
Total 32
Without ResourceAction
1.0 WS req WS res HTML [2]
1.1 WS req AS res [2]
1.2 WS req AS res [2]
1.3 WS req AS res [2]
1.4 WS req AS res [2]
1.5 WS req AS res [2]
1.6 WS req AS res [2]
1.7 WS req AS res [2]
1.8 WS req AS res [2]
1.9 WS req AS res [2]
1.10 WS req AS res [2]
Total 22
However, let me note, once again, that we can make it 22 to 22 by
simply sending the attributes that are relevant back to a different
server. For example, we could have
<img src='http://blahblahblah.com/ResourceAction.do?file=whatever.gif'>
Doing this, if we are talking about serving images to a large-scale
site, we could get rid of both the WS and the AS and use a SCS (small
custom server) optimized for this situation. I do this sort of thing
constantly, *sub rosa*, on my sites. This is probably quicker than
using WS to serve the images, and certainly so if the images are in
any way dynamic in nature and if we make use of the multithreading
opportunities that crop up in this situation. But, this is going
afield. And, this is only looking at the upside too.
