HTTP POST connection close - Problem

[Jaishree]

Problem:

 

 

when we are sending HTTP POST request (From C++ Program)- Connection got closed with "Connection reset by peer" mesaage after 5 transfers.

 

But , when we are doing a POST msg in the web browser, the same message getting accepted by apache. Not sure whether we are doing mistake in setting up the connection or some thing else.

 

Appriciate your time and advise on this.

 

Thanks

 

The c++ code snipet given below FYR...

 

{

sprintf(request,"POST /app-srv/read HTTP/1.1\r\nHost: 101.1.1.2:8080\r\nUser-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.0.12) Gecko/20070718 Red Hat/1.5.0.12-3.el5 Firefox/1.5.0.12\r\nAccept: text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5\r\nAccept-Language: en-us,en;q=0.5\r\nAccept-Encoding: gzip,deflate\r\nAccept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7\r\nKeep-Alive: 300\r\nConnection: keep-alive\r\nReferer: http://101.1.1.2:8080/app-srv/\r\ntreemenu=none open\r\n");

Did you not believe me the first time?

 

 

But, if that's not it, try outputting the stuff that you're sending.  Maybe you're missing a linebreak somewhere or something.

Thanks Corbin

 

I tried it out since i belived

But it didn't work

I set "KeepAlive: On" & "maxNumberof connection :100"    in httpd.conf

i guess the way proceed was correct

is it so?

 

is there any specific linebreaks that should be given after some bytes in the POST message  ??

 

Thank you

No, I meant maybe you're not following HTTP specifications, but I don't think that's it since it wouldn't work for 5 requests.

 

 

I set "KeepAlive: On" & "maxNumberof connection :100"

 

Those are valid httpd.conf flags x.x.

While sending more than 8192 Bytes of data , Reset Happens.

 

Is it related to "LimitRequestBody" Directive ???

 

If so , where i need to set this in Apache HTTP Server??
