We have a lot of links written as
homehighschoolhelp.com/blog/what-are-social-sciences

We need these to add an "s" to the word "blog" in each url
homehighschoolhelp.com/blogs/what-are-social-sciences

How would we write this in Redj?

Thank you

Thank you Luigi once again you nailed it!

I tried about 5 different variations before but I completely missed the concept of pathtrim.
I had the "From URL" perfect however I assumed in the "To URL" it would trim the url by itself without the pathtrim syntax.
I had it written as {scheme}://{siteurl}/blogs/{queryfull}
Now I realize from your rules that, in the "To URL" you must first instruct it to add the "s" with
"{scheme}://{siteurl}/blogs/" then instruct it to remove the original "blog" from the url with "{pathltrim /blog/}".
I do not yet understand what "{queryfull}" does.
I assume it is an instruction to query the entire URL not just part of it.
I will research it in your documentation.

Anyway thank you and now that I comprehend it more I should not have to bother you as much in the future.

Thank you very much Luigi
