How to get the 400 characters limit for URL field

Question

_{Thursday, November 14, 2019 9:40 AM}

Hi ,

We are using the URL field of Link to a document content type to store the url for link in SharePoint online App development.

We get issue for storing URL with more than 255 characters. From documentation it seems that now this limit is increased to 400 characters but we get this issue for SharePoint online

Can anyone suggest me a way to store URL with more characters? we want URL field only as user should be able to redirect to that url on click of link.

Thanks,
Swati

Hi Swati,

The old "maxpath" limit was 256 Unicode code units, but it now has been expanded to 400 Unicode code units, but the expanded maxpath limit only applies to unencoded URLs. "There is no limit to encoded URLs in SharePoint Online and OneDrive for Business,"

Please read the below article how it works:

Hi Swati.

Could you provide some examples of the URLs that are exceeding the 255 characters length?
The 400 characters maximum length applies only to unencoded URLs.

Hi, Swati,

Just as others said, this new limit section applies to the total length of the URL path to a folder or a file in SharePoint Online and OneDrive for Business but not to the length of any parameters. Also, these limitations apply only to un-encoded URLs, not to encoded URLs. There is no limit to encoded URLs in SharePoint Online and OneDrive for Business.

You can check it here:New MAXPATH limits in SharePoint and OneDrive

Hi,

Thanks.This is how we the url looks like

https://moor1.domainname.com:11443/testWeb/RetrieveDocument.do?r=xQiEj0XSE9qGDof58Jq+eI7zaISsPRnKmD7JvpO5kRCYvdIR7UoaSA==&repositoryID=K2tGORbcO8Y+9u+/R/7q5g==&sum=Y7KKxYyRBpftwxLrYIznQ54tyGw=&filename=Testdocsdsdjsdsdsdssdasasasassdssdsdsdsdsdssdsdsdsdsdsd.txt

We are assigning this value to Link to a document's URL column.

Thanks,
Swati

The link is not for sharepoint file. On click of link to a document we are redirecting it to some other server and this link is stored as a part of URL column of the link to a document.

Thanks,

Swati

Hi, Swati,

Here is a workaround you can try. Use the Multi line text column. You may need to do it in classic experience. Create a Multiple lines of text column, set it to Rich text or enhanced rich text. Then you can edit the column value. 

Go to the Multi-Text field and you will get Rich-Content Ribbon. Click Insert on the Ribbon > Hyperlink. Add your title and  long URL in the respected field. 

Best Regards

I need to programmatically do it using CSOM to update the linkitem["url"] and linkitem["_ShortCutURL"] fields.
