proxy recorded URL OK; now jmeter/httpclient balks during load test

[Will Milspec]

Hi all,

This is the first of two problems I found tonight.

I'm new to Jmeter having used primarily a lightweight tool called "wapt"

Here's the problem:
Some requests in my test fail with response code
"java.lang.IllegalArgumentException." It turned out this
"illegalargumentexception" occurs not on the server side, but in the java
httpclient


It appears to try to get this url:

    <java.net.URL>
http://site.company.com/pe/FileDownloadServlet?fileName=/img/members\member_10186952_1229535508021.gif
</java.net.URL>

then fails with this error:
    <responseData
class="java.lang.String">java.lang.IllegalArgumentException: Invalid uri
&apos;
http://site.company.com/pe/FileDownloadServlet?fileName=/img/members\member_10186952_1229535508021.gif&apos;:
Invalid query&#xd;
    at
org.apache.commons.httpclient.HttpMethodBase.&lt;init&gt;(HttpMethodBase.java:222)&#xd;

A few points/questions:
* The proxy recorded this url. Why did the proxy 'bless' the url, but
complain now?
* what specifically about the url is a problem? I would imagine it's the
backslash-members "\members"...

I've included the whole 'httpsample' entry as it may shed some light.

thanks in advance,
will
