Web users getting mixed/incorrect results

[Vinesh Dhevcharran_1]

Hi,

I have a library application ALEPH running on an HP L2000 and we use Apache 1.3.27

We sometimes get complaints that when a search is done on library A, results from library B is returned.

We have checked caching parameters on the disktops and on the DNS and go some success with this, however that problem is still not resolved.

Does the HP or Apache cache info. anywhere on the HP machine? and if so what can I do about it?

I seriously doubt that the problem is in the HP-UX. This leaves 2 likely scenarios.

1. Apache
* Misconfiguration is most probable cause
* bad site build is 2nd
* an actual bug with apache is last

2. Desktops
* Is disk cache on for the clients? if so is it small enough not to cache and retrieve bad data? (default IE is 50MB I think)
* Is memory cache on for the clients? if so is it small enough not to cache and retrieve bad data? (default is 15 or 20MB)

Normally, I start on clients. Either disable cache, or move it down to 2048K (2MB).

If this is not the case, start tracing the URL's that the clients hit, and check them. At the same time, make sure that your apache is up to date.

Also, is this SQL queary data? If so, ensure that the SQL the clients submit work from command line. It's easy to make small mistakes that cause the problems we only see sporadically.
