Appending query strings breaks URL #116

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. create a rewrite rule like the one below:
    <rule>
        <from>^/robots\.txt$</from>
        <to type="permanent-redirect" last="true" qsappend="true">/en/robots.txt</to>
    </rule>

2. Go to a URL which will be rewritten with the above rule, and make sure to 
use a query-string
    www.mydomain.com/robots.txt?param1=value1&param2=value2

3. Check the rewritten URL

After the rewrite we would expect to see the following URL:
    www.mydomain.com/en/robots.txt?param1=value1&param2=value2
but the "?" before the first parameter has been replaced with a "&"
    www.mydomain.com/en/robots.txt&param1=value1&param2=value2

We are using version 4.0.3 and tested on several operating systems.

Currently we fixed it ourselves by changing the code:

Class: NormalRule.java
Method: public RewrittenUrl matches(final String url, final HttpServletRequest 
hsRequest, final HttpServletResponse hsResponse, RuleChain chain) ...

Original line of code (line 99)
    ruleExecutionOutput.setReplacedUrl(target + "&" + hsRequest.getQueryString());

New code
    if (target.contains("?")) {
        ruleExecutionOutput.setReplacedUrl(target + "&" + hsRequest.getQueryString());
    } else {
        ruleExecutionOutput.setReplacedUrl(target + "?" + hsRequest.getQueryString());
    }

I'm seeing the same thing...

This works:
<to type="redirect" last="true">http://localhost:8080/$2?%{query-string}</to>
While this does not:
<to type="redirect" qsappend="true" last="true">http://localhost:8080/$2</to>

This looked like a great feature and was actually the reason I upgraded from 
v3.2.

Also, I'd love to see this option work so that it only appends '?' when there 
is a query string to append.  This would help me clean up my rules that are 
duplicated just for this reason.

Hi, any chance of seeing this issue in a release available via Maven Central? 
We're using some ugly workarounds right now w/ 4.0.4, and I'd love to see them 
go away...

Greetings.

I'm using 4.0.4. version and I have exact problem - urlrewritefilter replaces ? 
with & . Is there any chance to make new version with that fix?

Many thanks.

Hi, all. The fix has not been released with 4.0.4. It is in trunk, but not in 
4.0.4 release. Release is needed.

Two years later, still waiting for a new release fixing this issue... Is 
UrlRewriteFilter abandoned?
