Hi,

I am using the ISAPI-DLL with IIS5. For some reason I wanted to include a part of my pages final HTML-output in the session.

But with the next request after the output is written in the session, the session starts again and everything saved in it is lost.

Using PHP as CGI everything works fine.

More details :

Using the same Text (containing 58 CR/LFs in it) 
the IIS-Version shows ... ;s:2345:" ...
the CGI-Version shows ... ;s:2403:" ...

(The text including the CR/LFs is excactly 2403 bytes long)

I do not register the variable with the text directly to the session, instead I register 1 object with all my session-stuff in it, including this text.
Besides the string length there are no differences in the session-file with the CGI/ISAPI-version.

Please try latest CVS, I remember some patch dealing with this.

Sorry, the latest version I can test is the CVS from 01.08. because there exists a windows build, I am currently not able to build it myself.

In this version the problem is still the same as described.

Thanks to James Moore I was able to test the latest CVS-verion now :

The problem seems to be gone, the session doesn't restart anymore when adding the text to the it.
But the difference between the session-file using the IIS and the CGI version is still there as described.
So I don't know if this behaviour is intended, maybe one of the developers knows more about it.

What's the situation with this? Does this problem still exist
with the php4.0.2  (release) ? Or latest CVS?

Its still the same as with the 4.0.2 CVS I tried some time ago.

First of all, it doesn't make any problems, it still works.

The IIS-Version still writes another value in the session-file compared with the CGi-version (as described).

So it's just IIS which behaves differently. If I understood correctly,
this isn't any bug at all. And if it works the same..
