Url Rewrite 2 0 Rule Can Prevent Images From Displaying On Webcontrols Like Treeview
- 19 Mar 2010
I was excited to try URL Rewrite to create some rules on my internal web site. I added a rule to map a query string like http://mysite/treepage.aspx?nodeName=RedColors to http://mysite/RedColors . After doing this I found that the images of the treeview web control now did not display. I enabled FREB tracing and found that this rule was translating webresource.axd improperly:
<rule name=”RewriteUserFriendlyURL1″ stopProcessing=”true”>
<match url=”^([^/]+)/?$” />
<add input=”{REQUEST_FILENAME}” matchType=”IsFile” negate=”true” />
<add input=”{REQUEST_FILENAME}” matchType=”IsDirectory” negate=”true” />
</samp>
RequestURL http://mysite:80/WebResource.axd?d=zGZU6qcW6fzAgYe-oI85v1qoiSgWelpv1EkImgNZdKA1&t=633802488069218315
Since the rule saw the ‘?’ char it was trying to map it.
To solve this add a rule to exclude processing of .axd files:
<rule name=”RewriteUserFriendlyURL1″ stopProcessing=”true”>
<match url=”^([^/]+)/?$” />
<add input=”{REQUEST_FILENAME}” matchType=”IsFile” negate=”true” />
<add input=”{REQUEST_FILENAME}” matchType=”IsDirectory” negate=”true” />
<!– The following condition prevents rule from rewriting requests to .axd files –>
<add input=”{URL}” negate=”true” pattern=”\.axd$” />
