I get error's like this sometimes when I click a link in pier:
Error: "/seaside/mmiki/seaside/mmiki/A-Page" not found.
Notice the path is duplicated. I figure that this is an error that
occurs after the page time's out. yes?
How can I fix this? Why does this happen? Lukas mentioned a thread to
search for but I can't find that message (sorry!) and I haven't found a
good explanation.
Can anyone point me in the right direction?
thanks,
brad

Again this can be solved with a RewrtieRule that you put before
RewriteCond in your Apache config:
RewriteRule $/seaside/mmiki/(.*)^ http://localhost:9999/$1
[proxy,last]
The reason you need this is a problem of Seaside redirecting to the
wrong URL when a session has a timeout. Unfortunately this is not
that easy to fix. I did several attempts during the development of
2.7, but could not figure out a way that did not break a lot of other
applications altogether. Anyway, for now the above RewriteRule does
the trick.
Cheers,
Lukas

Bummer... I thought that there was something in the image so I wouldn't
have to write another rule, but now I remember you saying you
investigated this.
BTW: just to be clear the rule above has the "^" and "$" flipped
around.
Shouldn't it be:
RewriteRule ^/seaside/mmiki/(.*)$ http://localhost:9999/$1 [proxy,last]

OK, I admit this is a bit OT, but it does have something to do with
getting Seaside and Apache working together. Others might benefit too...
and I'm surprised that others don't see this problem.
Actually, one would think that the solution above would work, but in my
case it does not. In fact, sometimes I get the path repeated 3 times!
What I did was bypass apache, set the Pier app default timeout low and
go at it to see if I could find something useful. In every case of a
timeout, Pier worked fine when bypassing apache. After timeouts, seaside
went to the next page just fine. So, I think my issue is something to do
with apache. I thought maybe there is a cache problem on the server
side, so I made sure that no cache module is loaded. Why would the path
get duplicated so many times and KOM/Seaside work just fine?

That's strange this never occurred to me. Did you check the Apache
logs (access.log, error.log, rewrite.log)?
What I did was bypass apache, set the Pier app default
timeout low and
go at it to see if I could find something useful.
You could also evaluate
WARegistry clearAllHandlers
to expire all existing session at once ;)

=======================
For those interested (I suppose it's only me), Here are traces from the
rewrite log with different rewrite rules.
Modules loaded:
rewrite_module
proxy_module
proxy_http_module
No cache modules loaded
*No* other "proxy" directives used except below
*===TRACE 1=====
*ProxyPreserveHost On
RewriteEngine ON
RewriteRule ^/seaside/files/(.*)$ http://localhost:9999/seaside/files/$1
[proxy,last]
RewriteCond /home/web/mmiki/%{REQUEST_FILENAME} !-f
RewriteRule ^/(.*)$ http://localhost:9999/seaside/mmiki/$1 [proxy,last]
Result: at page timeout, it appears that seaside writes the path to the
Pier app, resulting in a duplicated path
[Start rewrite engine on request]
(2) init rewrite engine with requested uri /DonsTestPage
[is there a match with first rule?]
(3) applying pattern '^/seaside/files/(.*)$' to uri '/DonsTestPage'
[nope, check next rule]
(3) applying pattern '^/(.*)$' to uri '/DonsTestPage'
[yep, look at the condition before this]
(4) RewriteCond: input='/home/web/mmiki//DonsTestPage'
pattern='!-f' => matched
[nope, this isn't a local file, so rewrite it]
(2) rewrite /DonsTestPage ->
http://localhost:9999/seaside/mmiki/DonsTestPage
[and send it to seaside with the proper path]
(2) forcing proxy-throughput with
http://localhost:9999/seaside/mmiki/DonsTestPage
(1) go-ahead with proxy request
proxy:http://localhost:9999/seaside/mmiki/DonsTestPage [OK]
[but, then it continues - THIS MUST BE THE TIME OUT]
[Start rewrite engine on request]
(2) init rewrite engine with requested uri
/seaside/mmiki/DonsTestPage
[is there a match with first rule?]
(3) applying pattern '^/seaside/files/(.*)$' to uri
'/seaside/mmiki/DonsTestPage'
[nope, check next rule]
(3) applying pattern '^/(.*)$' to uri '/seaside/mmiki/DonsTestPage'
[yep, look at the condition before this]
(4) RewriteCond: input='/home/web/mmiki//seaside/mmiki/DonsTestPage'
pattern='!-f' => matched
[nope, this isn't a file, so rewrite it]
(2) rewrite /seaside/mmiki/DonsTestPage ->
http://localhost:9999/seaside/mmiki/seaside/mmiki/DonsTestPage
[and send it on it's way]
(2) forcing proxy-throughput with
http://localhost:9999/seaside/mmiki/seaside/mmiki/DonsTestPage
(1) go-ahead with proxy request
proxy:http://localhost:9999/seaside/mmiki/seaside/mmiki/DonsTestPage [OK]
*===TRACE 2=============*
If a rewrite rule is added to eliminate the path at the time out:
================
ProxyPreserveHost On
RewriteEngine ON
RewriteRule ^/seaside/files/(.*)$ http://localhost:9999/seaside/files/$1
[proxy,last]
RewriteRule ^/seaside/mmiki/(.*)$ http://localhost:9999/$1 [proxy,last]
RewriteCond /home/web/mmiki/%{REQUEST_FILENAME} !-f
RewriteRule ^/(.*)$ http://localhost:9999/seaside/mmiki/$1 [proxy,last]
Result: 2nd rewrite rule catches path but seaside really needs the path
to the Pier app.
(2) init rewrite engine with requested uri /DonsTestPage
(3) applying pattern '^/seaside/files/(.*)$' to uri '/DonsTestPage'
(3) applying pattern '^/seaside/mmiki/(.*)$' to uri '/DonsTestPage'
(3) applying pattern '^/(.*)$' to uri '/DonsTestPage'
(4) RewriteCond: input='/home/web/mmiki//DonsTestPage' pattern='!-f' =>
matched
(2) rewrite /DonsTestPage ->
http://localhost:9999/seaside/mmiki/DonsTestPage
(2) forcing proxy-throughput with
http://localhost:9999/seaside/mmiki/DonsTestPage
(1) go-ahead with proxy request
proxy:http://localhost:9999/seaside/mmiki/DonsTestPage [OK]
(2) init rewrite engine with requested uri /seaside/mmiki/DonsTestPage
(3) applying pattern '^/seaside/files/(.*)$' to uri

(2) forcing proxy-throughput with http://localhost:9999/DonsTestPage
(1) go-ahead with proxy request proxy:http://localhost:9999/DonsTestPage
[OK]
*===TRACE 3===========*
But,of course seaside needs the path to the app.
If the rewrite rule is written to add the path for the timeout
It works fine. Except the URL in the browser adds the path
===============
ProxyPreserveHost On
RewriteEngine ON
RewriteRule ^/seaside/files/(.*)$ http://localhost:9999/seaside/files/$1
[proxy,last]
RewriteRule ^/seaside/mmiki/(.*)$ http://localhost:9999/seaside/mmiki/$1
[proxy,last]
RewriteCond /home/web/mmiki/%{REQUEST_FILENAME} !-f
RewriteRule ^/(.*)$ http://localhost:9999/seaside/mmiki/$1 [proxy,last]
Result: 2nd RewriteRule adds the correct path, but the URL the client
receives includes the path. Not pretty.
(2) init rewrite engine with requested uri /DonsTestPage
(3) applying pattern '^/seaside/files/(.*)$' to uri '/DonsTestPage'
(3) applying pattern '^/seaside/mmiki/(.*)$' to uri '/DonsTestPage'
(3) applying pattern '^/(.*)$' to uri '/DonsTestPage'
(4) RewriteCond: input='/home/web/mmiki//DonsTestPage' pattern='!-f' =>
matched
(2) rewrite /DonsTestPage ->
http://localhost:9999/seaside/mmiki/DonsTestPage
(2) forcing proxy-throughput with
http://localhost:9999/seaside/mmiki/DonsTestPage
(1) go-ahead with proxy request
proxy:http://localhost:9999/seaside/mmiki/DonsTestPage [OK]
(2) init rewrite engine with requested uri /seaside/mmiki/DonsTestPage
(3) applying pattern '^/seaside/files/(.*)$' to uri
'/seaside/mmiki/DonsTestPage'
(3) applying pattern '^/seaside/mmiki/(.*)$' to uri
'/seaside/mmiki/DonsTestPage'
(2) rewrite /seaside/mmiki/DonsTestPage ->
http://localhost:9999/seaside/mmiki/DonsTestPage
(2) forcing proxy-throughput with
http://localhost:9999/seaside/mmiki/DonsTestPage
(1) go-ahead with proxy request
proxy:http://localhost:9999/seaside/mmiki/DonsTestPage [OK]
This is the desired path, but the URL in the client browser is incorrect:
It is:
http://igor:8080/seaside/mmiki/DonsTestPage?command=PRViewCommand&view=…
It should not have the "/seaside/mmiki" path, And, actually, this
doesn't work when you want to go back to the top in Pier after timeout.
Actually, one
would think that the solution above would work, but
in my
case it does not. In fact, sometimes I get the path repeated 3 times!

http://cmsbox.netstyle.ch/ seems to exhibit a problem too when it times out.
Although, it looks more like it uses ProxyPass instead of Rewrite rules.

No, it uses RewriteRules. It is basically the same setup everywhere.

I applied this rewrite rule as the first one:
RewriteRule ^/seaside/pier(.*)$ http://www.lukas-renggli.ch$1 [R,L]
Thanks Lukas, that seems to work.
The difference is the [R] from before to redirecting it back to the
domain name once again.
Again, thanks! What a headache that was!
