title: htaccess rewrite. always replace the the first part after domain
body: <p>My main API URL entry point is: <a href="https://www.sample-domain.com/abc/" rel="nofollow noreferrer">https://www.sample-domain.com/abc/</a>  and then I can have URI_REQUESTS which will follow, for e.g.: 
  <br><a href="https://www.sample-domain.com" rel="nofollow noreferrer">https://www.sample-domain.com</a><b>/abc/</b>
  <br><a href="https://www.sample-domain.com" rel="nofollow noreferrer">https://www.sample-domain.com</a><b>/abc/</b>?do=something
  <br><a href="https://www.sample-domain.com" rel="nofollow noreferrer">https://www.sample-domain.com</a><b>/abc/</b>john (with trailing slash or not..) 
  <br><br>
  I want to be alble always to rewirte to any request which has the first part of the URL diffrent back to /abc/. Examples:
  <br><a href="https://www.sample-domain.com" rel="nofollow noreferrer">https://www.sample-domain.com</a><b>/def/</b>  (with trailing slash or not..) 
  <br><a href="https://www.sample-domain.com" rel="nofollow noreferrer">https://www.sample-domain.com</a><b>/def/</b>?do=something or 
  <br><a href="https://www.sample-domain.com" rel="nofollow noreferrer">https://www.sample-domain.com</a><b>/def/</b>john 
  <br>
  I dont care how many parts the URL will have after the first part ot if it has trailing slashes or any query-strings I alwas want to change the first part following the domain back to /abc/  </p>
  
  <p>But certain first parts has to be ignored for examle if it comes in as sample-domain.com/help/ then it should not rewrite</p>
