issue with 18d gws

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) --2009-11-05 11:51: 08-- http://192.168.2.114:2480/base_c2.swf Connecting to 192.168.2.114: 2480... connected. HTTP request sent, awaiting response... HTTP/1.1 200 OK ETag: g1m02yog29nf Content-Type: application/x-shockwave- flash Content-Length: 105819 Date: Thu, 05 Nov 2009 11:51:08 GMT Connection: Keep-Alive Length: 105819 (103K) [application/x-shockwave- flash] Saving to: `base_c2.swf' 100% [==============================================================================================>] 105,819 --.-K/s in 0s 2009-11-05 11:51:08 (337 MB/s) - `base_c2. 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!

Hi Rama,
how do you configure server part to reproduce 1) or 2) issues? For example issue 1), how often you observe it, what kind of requests you do (some HTTP dump)? Unfortunately without testcases it will be difficult to fix something :(, but we can try to solve issues one by one, if you'll be able to provide more info. Thanks. WBR, Alexey.
