Title: Exclude query string Last modified: March 23, 2025 --- # Exclude query string * Resolved [VIDEGRAIN](https://wordpress.org/support/users/edouard2/) * (@edouard2) * [1 year, 2 months ago](https://wordpress.org/support/topic/exclude-query-string-2/) * Hello, * I’m using Omnisend for email campaigns and LiteSpeedCache with Cloudlare as Cache solution. * I would like to add an exclusion in the ‘Drop Query String’ of LiteSpeed Cache because when users click on a link of the email campaign the page is very long to download. * Can you confirm that a solution is to add omnisend in ‘Drop Query String’ àf LiteSpeed. An d if yes, what text should I add. For example : ‘omnisendContactID’ or ‘omnisend’ or ‘rie.soundestlink’ ? * Thank you in advance. * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fexclude-query-string-2%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 5 replies - 1 through 5 (of 5 total) * Plugin Support [supportomnisend](https://wordpress.org/support/users/supportomnisend/) * (@supportomnisend) * [1 year, 2 months ago](https://wordpress.org/support/topic/exclude-query-string-2/#post-18378186) * Hi [@edouard2](https://wordpress.org/support/users/edouard2/), * Thank you for bringing this up here on the WordPress forum! * Based on what you’ve described, we would suggest using the parameter `omnisendContactID` in the Drop Query String setting of LiteSpeed Cache. This parameter is included in every Omnisend campaign link and remains consistent, which makes it a reliable choice for exclusion. * After setting this up, we kindly recommend testing the change by sending a real campaign to yourself and checking how the landing page performs. * Let us know how it goes — or if you have any follow-up questions that we might cover from our side. We’re here to help make things run as smoothly as possible! * Thread Starter [VIDEGRAIN](https://wordpress.org/support/users/edouard2/) * (@edouard2) * [1 year, 2 months ago](https://wordpress.org/support/topic/exclude-query-string-2/#post-18381746) * Thank you for this answer. It seems to be faster now. * Also, I would like to know what can be done to reduce loading time for omnisnippet1. com and wt.omnisendlink.com. * Do you have any advice to reduce this delay (measured with Uptrend) ? - This reply was modified 1 year, 2 months ago by [VIDEGRAIN](https://wordpress.org/support/users/edouard2/). * Plugin Support [supportomnisend](https://wordpress.org/support/users/supportomnisend/) * (@supportomnisend) * [1 year, 2 months ago](https://wordpress.org/support/topic/exclude-query-string-2/#post-18383041) * Hi there, * You’re most welcome [@edouard2](https://wordpress.org/support/users/edouard2/)— it’s great to hear things are already feeling faster! * Regarding the loading time for `omnisnippet1.com` and `wt.omnisendlink.com`: our script (or JS snippet) uses [lazy loading, also known as asynchronous load (asyncLoad)](https://en.wikipedia.org/wiki/Lazy_loading). This means it’s intentionally loaded at the end of the page load process, so it doesn’t interfere with the loading of your site’s core files. * As a result, the speed at which our snippet loads can depend quite a bit on how optimized the rest of the site is. A lightweight, well-optimized website — with fewer blocking scripts, smaller image sizes, and efficient use of CSS/JS — will allow our script to load and execute more quickly. * We hope this helps clarify things and gives you a better sense of what’s going on behind the scenes. * Let us know if you have any follow-up questions — we’re happy to help! * Thread Starter [VIDEGRAIN](https://wordpress.org/support/users/edouard2/) * (@edouard2) * [1 year, 2 months ago](https://wordpress.org/support/topic/exclude-query-string-2/#post-18383076) * Hello, * Thank you for your answer.
