Re: emulating enable_trans_sid

Hi Ok probably the easiest is just to add <?if(!empty(SID) echo 'sid='.SID?> to the end of each url, if cookies are supported SID will be an empty string. Tom At 01:59 PM 1/07/2002 +1000, you wrote:

I'm aware of this. What I'm trying to do is emulate this process on servers which have not compiled with --enable_trans_sid. I thought that was pretty clear, but perhaps not. In the ideal world, enable_trans_sid would have been compiled, but I'm yet to find many shared hosts where this has been done. And since shared servers seem to be what my current client set are using, I'm looking at emulating enable_trans_sid.

Hi, As discussed a few months back, I'm interested attempting to recreate

PHP's

enable_trans_sid feature, for users without cookies. ONLY if cookies are UNavailable, I want to open the output buffer,

build the

page, then run a reg exp or something over the output to append SIDs

to all

URLs (GET), then print it. I've got a pretty good picture in my head of how I'll test for

cookies, and

how I'll do the output buffering, but regexp's are NOT my thing :) I'm interested in hearing some opinions on the most efficient way to

append

the SID to all internal URLs on the page... this would include: - header("Location: something.php") - <A href="something.php"> - <FORM action="something.php"> My thoughts are that it would only be done for relative links (dir/something.php), NOT for fully qualified URLs (http://otherdomain.com, ftp://, mailto:, https://, ?????), as per enable_trans_sid documentation. It would also have to accommodate URLs which already have a query

string...

if there's an existing query string, just append &SID, otherwise append ?SID. This seems to me like a rather in-depth regexp already, and I'm sure i'm forgetting something. Perhaps there's a simpler way that I'm missing? The only simpler way

I can

think of would be to search for '.php' and '.php?' and act

accordingly, but

this has obvious problems when 'something.php' is type, but not in context of a link or header redirection. Where would I look to see the source of enable_trans_sid -- maybe this

will

give me some hints?? Justin French -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
