Hello! Trouble with caching $_SESSION ( fixed!!! )

I have site on MODX Revolution 2.1.5-pl (traditional) and BobRay's package captcha.
If call Captcha (assets/components/captcha/captcha.php) she olways set session var $_SESSION["veriword"] is equal of image on she.
But, modx get $_SESSION from cache in DB (table modx_cache if prefix modx_)...

Thus, the image (assets/components/captcha/captcha.php) is always different, but the value of the cache is stored verivord a while the old and same...

Help please, how disable caching $_SESSION, or olways rewrite one var $_SESSION['veriword'] ?

Thank you!

>>>===<<<

My hosting conflicting with modSessionHandler. On another hosting worked... But i dont know which is why it did not work...

But i disable his (modSessionHandler) on manager -> System -> System Settings -> session_handler_class -> clear value...

And all works.

Yhanks All for help! [ed. note: Petja last edited this post 14 years, 11 months ago.]

Petja, I'm unable to make this happen on MODX 2.1.5.

Are you using SPForm or FormIt, or your own code to call the captcha utility? Make sure any snippet calls are uncached:

I would think that every update to the SESSION, such as the change made when using a veriword feature, would clear that table's cache?

The query cache does not return stale data. When tables are modified, any relevant entries in the query cache are flushed.

Seems trouble in this!
It is only necessary to understand how to disable caching for this table only.

Spasibo!

The entire cache_db feature in MODX 2.1.x is broken. Just disable cache_db.

I'm sets in my.cnf
set-variable = query_cache_limit=0
set-variable = query_cache_size=0

Now still does not work, caches session...

How disable caching only one variable $_SESSION['veriword'] ?

Even if it will turn off query_cache - server will slow down...

cache_db => No
cache_db_expires => 0
cache_db_session => No
cache_db_session_lifetime is empty

this was...

Now
mysql> show variables like 'query_cache_size';
+------------------+-------+
| Variable_name | Value |
+------------------+-------+
| query_cache_size | 0 |
+------------------+-------+
1 row in set (0.00 sec)

mysql>

But veriword again cached...
