Hi all,
after an update to gws 1.9.18d, from 1.9.16 i have noticed
some issue that i want to share with you
1)
when i do a request for
a certain page (that should return a big xml) i got
<fancy xml>
<blabla/>
<blabla/>
<blabla/>
Http header (!?!?!)
<blabla/>
<blabla/>
<blabla/>
</fancy xml>
this bug was already present in the past, and
if i remember well was a problem with http1.0 or something like that (i
don't know if this is till the case)
In any case, what's happen is that
the header are sended after a piece of request is issued :(
2)
wget
issue
if i do a
prometeo:~# wget -S -v
http://192.168.2.114:
2480/base_c2.swf
this is the output (correct)

swf' saved [105819/105819]
but, if i do the same command 2-3 times,
wget need to retry it 3 times before correctly get the base_c2.swf...
this is really strange because the pc is obviusly the same machine
(wget machine is the machine that host GWS) and there is noone
connected to that machine, so servicing this file should be
always a
success without any retry! also, as a side note, i simply execute wget
3-4 times (UP arrow enter) and they should't be concurrent afaik
3)
this is the most difficult to explain and reproduce...
internet
explorer 8 only bug :S
a bit of history on how the system work
i have 2
connection a <push over pull> and a <normal pull> request
so,
basically, on flash i have 2 different connector that work as follow
<PULL> ---> GWS ---> <RESPONSE>---> CLIENT
<PUSH> ---> GWS ---> WAIT
TILL EVENT---> <RESPONSE>---> CLIENT
this always worked like a charm,
on .16
this kind of work is handled via a asyncexecutorservices, btw.
unfortunatly with .18d what's happen is that
after a couple of refresh
of the browser, the socket doesn't work anymore in an indipendent way,
and every request seems to be serialized.
i had the idea that the issue
was on keepalive, but probably i was wrong.
what solved the problem,
was to put a lighttpd with a mod_proxy before GWS webserver :S
this
isn't really convenient.
If you need more help, let me know,
unfortunatly i can't provide any test case, due to the difficulty of
reproduce such kind of error :(
i have already try with a plain
webserver, but try to implement a push over pull and a pull for flash
is quite a long work :(
take care!
