Re: how to disable (or work around) jsessionid in html:img sources

[Ruth, Brice]

Bizarre ... dunno what's up with my config, then. Not a biggie, I guess 
- my workaround still works, I guess. I just wanted to use this because 
I was using a scriptlet to generate some *very* dynamic code and got 
into a situation where I couldn't use <html:rewrite> because it'd be 
nested within an <html:link> tag (in an onmouseover attribute) - so I 
wanted to use that code to get the prefix to just insert with another 
scriptlet. But, I think I've worked around that now, too.

It is truly amazing how a JSP can be compiled from custom JSP tags 
(tiles, struts, etc.), java code scriptlets, and EL expressions within 
tags, to something that actually works. I am truly amazed at times! :)

The jsessionid path parameter will only be added if the servlet
container
does not know whether your client supports cookies.  How Tomcat handles
this (probably typical of others):
* On the first response in a session, send the session id
both ways (cookie and encoding).
* If the subsequent request comes back with a cookie, turn
of URL rewriting for the remainder of this session.
* If the subsequent request comes back without a cookie,
keep on rewriting.

So, with that having been said, all you have to do is 
tell all your users to hit refresh whenever they access 
your site.  

That way, all external links and images will work.

If you find that unacceptable, you could:

Move the contents of index.jsp to index2.jsp, then:

Put a meta refresh tag as your initial page (index.jsp).
  <META HTTP-EQUIV="refresh" 
    content="2;URL=http://www.yoursite.com/index2.jsp";> 

or

Add some javascript that sends the user to index2.jsp.
  (similar to above)
or

Use <logic:redirect> or any number of ways in a scriptlet
to redirect to index2.jsp
On the Struts-Atlanta web site (http://www.struts-atlanta.org), 
I take a slightly different approach.
At the top of my index.jsp, I do this:

<logic:present parameter="refresh">
<bean:parameter id="refreshed" name="refresh"/>
</logic:present>
<logic:notEqual name="refreshed" value="true">
<logic:redirect page="/index.jsp?refresh=true"/>
</logic:notEqual>
What this does is refresh the page one time only.  This method works for
me because I am not posting or processing any forms with this page which
would not work correctly if I had.
Hope that helps.



     

Thanks, James.

Ignoring for the moment how these workarounds smack of "hack", this 
doesn't solve the problem of people visiting the site w/o cookies 
enabled. What I don't understand is why the delimiter ';' is being used, 
instead of the traditional '?' - which Apache wouldn't have a problem 
stripping off and serving up the proper file with ...

Just to clarify - by calling these workarounds "hacks" - I mean no 
disrespect - I am just looking for a cleaner method of handling this. 
That's all.
