Regex in Tuckey UrlRewrite

Question

I am using Tuckey URLRewrite and I need a rule which accepts everything except "/" or "\\"

I have wrote a rule but tuckey shows unending exceptions and doesn't load the page

    <rule>
        <from>^/post/([^/\n\\]+)/type/([a-z]+)$</from>
        <to>/post/?slug=$1&amp;type=$2</to>
    </rule>

From regexr I have verified that this expression "([^/\\n\\]+)" will select everything except "/" or "\\" But i am getting exceptions. Am I missing something?

Here are the exceptions:

Answer 1

OP had rules like this:

<rule> 
<from>^/post</from> 
<to>/post/</to> 
</rule> 

<rule> 
<from>^/post/([^/]+)</from> 
<to>/post/?slug=$1</to> 
</rule> 

<rule> 
<from>^/post/([^/]+)/type/([a-z]+)$</from> 
<to>/post/?slug=$1&amp;type=$2</to> 
</rule> 

Clearly the problem is ordering of rules here. Since first pattern: ^/post is overriding anything that starts with /post and causing below patterns like ^/post/([^/]+)/type/([az]+)$ to be ignore completely.

These rules need to be reordered like this:

<rule> 
<from>^/post/([^/]+)/type/([a-z]+)$</from> 
<to>/post/?slug=$1&amp;type=$2</to> 
</rule> 

<rule> 
<from>^/post/([^/]+)</from> 
<to>/post/?slug=$1</to> 
</rule> 

<rule> 
<from>^/post</from> 
<to>/post/</to> 
</rule> 

ie Keep generic catch-all type rules below specific targeted ones.
