Problem with nginx

[biff31337]

Starting with version 1574 hyperserver and app did start to thow problems, i think there is a problem with websockets.

Server looks like this, but no error in browser console. It works without reverse proxy.

nginx config:

location ~ / {
    proxy_pass http://127.0.0.1:8078;
    proxy_set_header Host             $host;
    proxy_set_header X-Real-IP        $remote_addr;
    proxy_set_header X-Forwarded-For  $proxy_add_x_forwarded_for;
    access_log off;
}

 

I tried to disable the websockets in hyper_server.cfg but no success. Also my client app does not work correctly.

ok, i get an error:

In the final program, it also does not load the content of unidbgrids.

the HandleEvent function returns:

_clat_();window.onunload=null;try{enableWarnOnClose(false)}catch(e){};window.location="xxx";

instead of:

{"metaData":{"totalProperty":"results","root":"rows","fields":["0","_0","1","_1","2","_2","3","_3","4","_4","5","_5","6","_6","7","_7","8","_8","9","_9","10","_10","11","_11","12","_12","_s4","_sa4","_s11","_sa11","_x","_r"]},"success":true, "results":1, "rows":[{"id":0,"0":0,"_0":"","1":"Purged","_1":"{b:'#FFC0C0',fc:'#000080',fts:'font-weight:bold'}","2":"0:00:05:18","_2":"","3":64,"_3":"","4":1,"_4":"","5":4248,"_5":"","6":"pluggit.exe","_6":"","7":"","_7":"","8":"1.0.0.0","_8":"","9":"15/11/23 13:00:00","_9":"","10":"1.95.0.1575 - 7.5.1","_10":"","11":"0.00 MB - 61.48 MB","_11":"","12":"","_x":1,"_r":0,"_s4":"1\x3Cbr\x3E(2)","_sa4":"{fc:'#808080',fts:'font-weight:bold'}","_s11":"0.00 (0.01) MB\x3Cbr\x3E61.48 (61.48) MB","_sa11":"{fc:'#808080',fts:'font-weight:bold'}"}]}

Hello,

Your exe complied with 1574 too?

Hello,

Do all dbgrids in your application work normally?

Yes, it happens because Sessions ID is missing in GET request. Starting from build 1574 session id is embedded in HTTP headers instead of being part of the URL. It seems that proxy server doesn't pass HTTP headers for GET requests.

Hello,

Thank you for your reply. Application and hyperserver is 1575. All DBGrids don't work.

[biff31337]

i tried proxy_pass_request_headers on; but no success so far....

[Farshad Mohajeri]

We may add an option to make sending session id through GET headers optional.

[biff31337]

could the problem be related to underscores in headers?

[Farshad Mohajeri]

Can you please check Request Headers for GET request to see if a parameter named _S_ID is there?

[biff31337]

looks like

[Farshad Mohajeri]

Is this your session id? Can you check by looking at web page source?

[biff31337]

yep

[Farshad Mohajeri]

Is this a session with working grids?

[biff31337]

It's the session for hyperserver web admin

[biff31337]

same problem with my application, it also shows (different) session ID

[Farshad Mohajeri]

Behind nginx?

In above example session ids were the same.

yes, both are from hyperserver. the app uses different one.

[biff31337]

http://nginx.org/en/docs/http/ngx_http_core_module.html#underscores_in_headers

this might be the source of the problems?

[biff31337]

yep, underscores_in_headers on; did the trick, maybe you should pass the session ID without underscores in future releases...

So problem is related to field name which is "_S_ID" ?

[biff31337]

It's releated to the underscore, it's disabled by default nginx config
