Re: HTTP Request Header & Data Handling

nsIRequest.

you can use nsIObserverService to hook your application up to receive 
notifications about HTTP requests and responses.  
nsIHttpProtocolHandler.idl documents these observer topics.

see the online xpcom book 
(http://www.mozilla.org/projects/xpcom/book/cxc/) for more info on using 
nsIObserverService to intercept various Gecko events.

if you have any questions, don't hesistate to ask.

Alright, but I don't understand how mozilla send parameters to HTTP 
servers. I mean there are two common ways to send informations :

1) GET for URLs
http://www.some-site.com/some-page.ext?param1=value1&param2=value2
HTTP request look like :
GET /some-page.ext?param1=value1&param2=value2 HTTP/1.X
...
2) POST for FORMs
http://www.some-site.com/some-page.ext and then there is something in 
request content.
HTTP request look like :
GET /some-page.ext HTTP/1.X
...
\n\n
====================someseparator============
param1=value1
====================someseparator============
param2=value2

I known all HTTP request fields are accessible like user-agent, 
referrer, host, ... But then for user-parameters can I access them the 
same way as common HTTP-parameters ?

I mean can I use nsIHTTPChannel::GetRequestHeader(...), 
nsIHTTPChannel::SetRequestHeader(...) and 
nsIHTTPChannel::VisitRequestHeaders(...) to check and then modify 
user-parameters ?
