Re: [OT] Examining Response Headers

[Adam Hardy]

Allow me to show off my neat request debugger method then, it's what I 
use for logging the stuff. I have it in my base action class and switch 
it on or off by the logger level. But you could put it in a JSP instead 
(with HTML). Specify if you want to see the request params, headers or 
attributes, and if you want plain text or HTML.

    /**
     * Extracts all request properties and values from request and puts
     * them in
     * an UL for display or in plain text
     *
     * @param request     the HTTP Request
     * @param doParams    enumerate the request parameters or attributes
     * @param inHtml      compile with HTML tags or not
     * @return a String containing each param name-value pair, in an 
>UL<

Adam, thanks. I did that. The problem is that I need to see request and
response headers from different browsers.

here's my suggestion: Firebird or Mozilla browser with LiveHttpHeaders
extension.

Robert,

DevProxy is a great program for monitoring the request and
response headers:

I recently did some socket programming.  DevProxy was an
invaluable tool.  You can see exactly

what flows through the socket between browser and host.  Very
good GUI interface.

Sorry for the OT post, but Googling and searching the mailing
list archives are not producing

much.
I may not be asking the right question though.
Anyhow, I need a tool (free) to examine the request and
response headers.

Any suggestions?
