looping of apache redirect

its kind of looping

in short i don't want to redirect my directory /l/apache/cgi-bin/application

as i write my cgi application which i want throw to customer so that i can collect user information

Rahul  

there was a typo in first part...instead of www.abc.ccom  it should be www.xyz.com

RewriteRule .* /v/xyz.com/asg/offline/offline.html [L]
means everything is redirected to offline.html


can i add some exclude condition , that don't redirect
/l/apache/cgi-bin/ directory to offline.html

just to prevent my looping issue

>but due to my rewrite rule it throws offline.html page as this url is coming from www.xyz.com
Where did you place the rules?

this will prevent looping and apply only for abc.com:
# If this global file exists, we're offline.
RewriteCond %{HTTP_HOST} ^(www\.)?abc\.com
RewriteCond /v/xyz.com/asg/offline/offline\.html -f
RewriteRule !offline\.html$|cgi-bin /v/xyz.com/asg/offline/offline.html [L]

the last line must be
RewriteRule !offline\.html$|!cgi-bin /v/xyz.com/asg/offline/offline.html [L]

can u please explain me what this means    !offline\.html$|!cgi-bin

i still want to confirm my requirement:

the existing rule:
RewriteCond /v/xyz.com/asg/offline/offline..html -f
RewriteRule .* /v/xyz.com/asg/offline/offline.html [L]

this redirects everything from www.abc.com/....... to offline.html page.

the contents of my offline.html page is
<META HTTP-EQUIV="Refresh"   CONTENT="5; URL=www.abc.com/cgi-bin/rahul.cgi">

so what is happening is even this gets redirect to offline.html since it is starting wth www.abc.com

i want to prevent this looping scenario

also complete path for my cgi file is in /l/apache/cgi-bin/rahul.cgi

>can u please explain me what this means    !offline\.html$|!cgi-bin

filepath contains not offilne.html at the end or filepath contains not cgi-bin

> also complete path for my cgi file is in /l/apache/cgi-bin/rahul.cgi
The complete path is not seen by the pattern of the rewrite rule, it just sees the filepath, i.e. in httpd.conf /cgi-bin/rahul.cgi, in /.htaccess without the leading slash cgi-bin/rahul.cgi

do i need both !offline\.html$|!cgi-bin  or just !cgi-bin

as my offline.html page itself contains redirect to my cgi-bin

where did you place the rules? It depends on that. If you placed the rules in per-dir context (.htaccess, inside <Directory> or <Location> of httpd.conf, you'll need this to prevent looping.

i tried both

as soon as as it sees the offline.html file in /v/xyz.com/asg/offline/    it throws offline.html also my offline.html gets redirected to www.abc.com/cgi-bin/rahul.cgi 
which i can see in the browser.
but i get the error:

Method Not Allowed
The requested method POST is not allowed for the URL /cgi-bin/rahulenv.cgi.


when i remove offline.html from /v/xyz.com/asg/offline/  and manually try www.abc.com/cgi-bin/rahul.cgi   it works fine

contents of rahul.cgi is:
#!/usr/local/bin/perl
##  printenv -- demo CGI program which just prints its environment

print "Content-type: text/plain\n\n";
foreach $var (sort(keys(%ENV))) {
    $val = $ENV{$var};
    $val =~ s|\n|\\n|g;
    $val =~ s|"|\\"|g;
    print "${var}=\"${val}\"\n<br>";
}

i have placed rules in :
offline.merchantaccount.conf

Check your browser headers i.e. with LiveHTTP-Headers for firefox, it looks like your browser is sending a POST-Request on <META HTTP-EQUIV="Refresh"   CONTENT="5; URL=www.abc.com/cgi-bin/rahul.cgi">.

Can you access www.abc.com/cgi-bin/rahul.cgi directly through your browser if offline.html exsists an the rewriterules are in place?

my modified rewrite rule
RewriteRule !offline\.html$|!cgi-bin /v/blah...../offline.html [L]

also the offline.htm exists in the directory....

i cannot access the www.abc.com/cgi-bin/rahul.cgi

same error i m getting from both mozilla and IE


as soon as i remove offline.html page   ---------- then no errror and the cgi works fine

may be can i specify complete url in rule (just guessing never done before)

RewriteRule !www.abc.com/cgi-bin/rahul.cgi /v/blah...../offline.html [L]

hi caterham_www

only !cgi-bin   worked   :-)

now only more issue

actually www.abc.com/cgi-bin/rahul.cgi  has a submit which redirects to www.abc.com/cgi-bin/test.cgi

i

oops!!! forgot

even test.cgi is is in same directory cgi-bin  so i assume that won't be redirected.....

let me try and will tell u

here is the last isseu


in my offline.html i m redirecting it to www.abc.com/cgi-bin/rahul.cgi

as i told u earlier rahul.cgi has a button...print "<html> <form action=http://abc.com/cgi-bin/customers.cgi> <input type=submit value=submit></form></input>";

the issue is when i click the button, its looping now and again goes back to www.abc.com/cgi-bin/rahul.cgi


once i get rid of this issue, i m all set.....

hehe

i found the solution

i have to add:

RewriteCond %{REDIRECT_URL} !^/cgi-bin

one thing is, even after i remove offline.html file, i have to manually delete the cookies and clear the cache from the browser....otherwise it still keeps on redirecting

why??

There seems to be sthg. wrong with request_uri, this is not normal.

This is a browser issue and a common problem on testing envrionments. The Browser tries to load pages from the local browser cache. The server responds with a 404 but the page is being loaded from the local cache.
