FAQ: In cases of complex views with many filter conditions selected, there may be instances where URLs copied using the URL copy button cannot be opened.
## Answer
Edit the IIS configuration file "web.config". IIS will RESTART when the changes are saved.
---
## Overview
In cases of complex views with many filter conditions selected, there may be instances where URLs copied using the "URL copy button" on the left side of the breadcrumb list cannot be opened. One possible cause is that the query string may have reached the maximum character limit that IIS can accept. The maximum character limit for query strings that IIS can accept is set by the parameter maxQueryString in the IIS configuration file "web.config", with a default value of 2048. By changing this value, you can enable URLs to open properly.
When set up according to the manual, web.config is located at C:\web\pleasanter\Implem.Pleasanter\web.config.

## Notes
1. IIS will RESTART when the edited web.config is saved. Please perform this procedure during a time when service downtime is acceptable.
1. The web.config file will be overwritten when Pleasanter is upgraded, so it needs to be configured again.
## Operation Procedure
1. Open web.config with a text editor such as Notepad.
2. Search for strings like "requestFiltering" to locate the section to edit. Once found, make the following changes:
Before change (excerpt)
```
<requestFiltering>
<requestLimits maxAllowedContentLength="2147483647" />
</requestFiltering>
```
After change (excerpt)
```
<requestFiltering>
<requestLimits maxAllowedContentLength="2147483647" maxQueryString="4096" />
</requestFiltering>
```
3. When you save the changes, IIS will RESTART.
4. Please verify the operation of the URL copy button.
