Apache caching

Problems with the Windows version of XAMPP, questions, comments, and anything related.

Apache caching

Postby shortmort37 » 08. February 2016 14:46

XAMPP is working beautifully for me! I copied my production phpBB board to my local computer, C:\xammp\htdocs - then loaded a database backup into MySQL. It all works flawlessly! Now I can test changes locally before I port them to production.

I'm having problems with the persistence of changes, though. If I edit a file, relaunch the page and examine the source, it corresponds to an earlier version of the file. I tried an Apache stop/start, to no avail. Is Apache caching, and if so, is there a way for me to turn that off?

Thanks
Dan

Either phpbb defines caching or your browser.
Xampp does not define any Apache caching rules.
We don't provide any support via personal channels like PM, email, Skype, TeamViewer!

My test code is in a subdirectory of my phpBB root, and is not known to phpBB - it's not in the phpBB cache. I've cleared by browser cache, several times.

I didn't modify anything with the standard distrib, but I know that Apache can cache: https://httpd.apache.org/docs/2.2/en/caching.html

I'm not sure how to diagnose my problem. I'm open to suggestions...

He didn't say Apache can't, he just was saying that by default XAMPP is not set to have Apache cache. I see a few possibilities.
- Browser cache: Ensure you clear the cache with all browser windows closed. Double check processes to see if browser is still running but "hidden"
- Wrong files: Check that you are in fact editing the correct file. Maybe you have copied the files in more than one location. Verify your url is requesting the correct location.
- Source files using live: It may be that your files or database have hard coded url to live files. Check that your access log does in fact receive a call and status 200 for each time you load the page.
- Included setting: Check that you don't have a .ini or other configuration file included from the source index/settings which may override your XAMPP setup.

What makes you so sure about that? Maybe phpBB caches everything what is stored under the phpBB root directory (that would a typical behaviour for caching). I dont think that phpBB is working with kind of file list, it simply caches everything what is requested in a certain scope. Just to be sure: there is cache folder under phpBB, you should clean up that folder (i.e. delete all files).

I cleared the phpBB cache.

Same behavior.

Are you sure you are calling/updating the right file? There is no caching from Xampp or Apache, when i change a HTML/PHP file, i simply need to reload it in my browser to see the changes. On all servers i manage (quiet a few).

I manage two phpBB boards myself. I know all about clearing the server side cache after an update, and clearing the browser cache. And I know what I edited. I can open the very file with my edits and display it side by side with the browser "view source". They are different.

I'm new to XAMPP, so I can guess I'm doing something wrong. What I *can't* guess, is exactly what it *is* that I'm doing wrong. I wish I had a path for diagnosis.

There is nothing you can do wrong in Xampp. Definately not. I dont know, what your are doing, and i dont know, what you are doing wrong. But anyway, it is not a Xampp issue.
