How to disable cache on specific links via htaccess?

01 - I would like to disable the browser cache for a specific link.

For example:
In wordpress, if you search for a term, "test" the search result will display the url:
htt ps://site . com/?s=test

I want to disable the cache for all links that start with:
htt ps://site . com/?s=

In this way, search results would never be cached.


02 - I would like to know if it is possible to have more than one cache rule, where each rule was used depending on a condition.

For example, on a wordpress site, when accessing the site, the htacces rule would check if you hear any changes to the site since the last visit.

* If there was no change, the browser cache will be used.

* If there was a change, the cache would be disabled, so the browser will search to download the updated version of the files.


03 - Where can I find a manual or something, explaining how to use htaccess programming, I couldn't find it on the web. I always find ready-made codes, but I can't find explanations of the meaning of each part.

Thankful.

 

You can try this below script:

<Directory /some/real/path/to/tmp>
Header Set Pragma "no-cache"
Header Set Expires "Thu, 1 Jan 1970 00:00:00 GMT"
Header Set Cache-Control "max-age=0, no-store, no-cache, must-revalidate"
Header Unset ETag
FileETag None
</Directory>

 

Hi. Daniel, thanks for your help.

I tried to add your code but I got error 500 in every attempt I made, see what I tried:

I try this on end of my htaccess:
<Directory /?s=>
Header Set Pragma "no-cache"
Header Set Expires "Thu, 1 Jan 1970 00:00:00 GMT"
Header Set Cache-Control "max-age=0, no-store, no-cache, must-revalidate"
Header Unset ETag
FileETag None
</Directory>

I try this too
<IfModule mod_expires.c>
# Enable expirations
ExpiresActive On
# Default directive
ExpiresDefault "access plus 1 month"
# My favicon
ExpiresByType image/x-icon "access plus 1 year"
# Images
ExpiresByType image/gif "access plus 1 year"
ExpiresByType image/png "access plus 1 year"
ExpiresByType image/jpg "access plus 1 year"
ExpiresByType image/jpeg "access plus 1 year"
ExpiresByType image/webp "access plus 1 year"
ExpiresByType image/svg+xml "access plus 1 year"
ExpiresByType image/x-icon "access plus 1 year"
# Video
ExpiresByType video/mp4 "access plus 1 year"
ExpiresByType video/mpeg "access plus 1 year"
# CSS, JavaScript
ExpiresByType text/css "access plus 1 month"
ExpiresByType text/javascript "access plus 1 month"
ExpiresByType application/javascript "access plus 1 month"
# Others
ExpiresByType application/pdf "access plus 1 month"
ExpiresByType application/x-shockwave-flash "access plus 1 month"

<Directory /?s=>
Header Set Pragma "no-cache"
Header Set Expires "Thu, 1 Jan 1970 00:00:00 GMT"
Header Set Cache-Control "max-age=0, no-store, no-cache, must-revalidate"
Header Unset ETag
FileETag None
</Directory>

</IfModule>



Remembering that I want all search results not to be cached.
That is, all URLs that begin with "MyDomain /?s=" they must not be cached...

MyDomain /?s=search1
MyDomain /?s=search2
MyDomain /?s=search3
MyDomain /?s=search ...



As explained, this is necessary for searches to always return updated results.
